Don't - Have any other programs open.

Spoiler

Many people like to have multiple programs open but, duh, this uses more cpu and ram and will slow down Minecraft.

Don't - Leave your laptop unplugged.

Spoiler

This don't is for laptop users so desktopers can skip this. Laptops are preset to perform less when unplugged to save battery. Leaving it plugged in won't boost your fps much, but it definitely helps. You can also set your laptop in the power settings to basically blow your fuse box and set performance to max. This may cause your computer to heat more though, which can hurt performance.

Do - Play on "fast" and "tiny" graphics, use Advanced OpenGL!

Spoiler

This is the easiest way to get more fps. What do they mean exactly? Well "fast" graphics changes the leaves from see through to solid, and subtly changes water and grass. Having see through leaves makes the computer render more, killing fps. Fog reduces how much the computer renders. You can't see as far the more fog you enable but you'll more fps. "Fast" and "tiny" are for the worst computers, giving you the most fps possible. 24 FPS is good for most people.

Advanced OpenGL seems to confuse many people. What it does is enable occlusion culling which is fancy talk for saying it's not going to render what you can't see. Provided your graphic card/drivers are compatible. In some cases this can even double fps (Very rarely triple). But if you are using an integrated chipset (I.E. Intel GMA) you cannot use it.

You can also set performance to "max fps", "balanced", and "power saver". "Power saver" will use less resources from your computer and will reduce fps , "balanced" is in between "power saver" and "max fps", and "max fps" will use as much power as possible and give... well... max fps, which is what you want if you have a slow computer. This can also be used as an fps limiter if you have a good computer. "Power saver" sets it to 40 FPS, "balanced" is 90 FPS, and "Max FPS" is 200 FPS. The framerate will only be capped when there are any chunk updates (except for the 40 FPS setting), and allow for faster chunk loading. It's a matter of opinion on how much FPS is enough. But the most you will ever need is 60. Keep in the mind the higher the FPS the harder your machine is working and the hotter it's going to get.

Don't - Use texture packs bigger than 16x, which is the default resolution.

Spoiler

Anything more will need more memory and slow you down. And oddly enough some texture packs will boost your fps. For me Jehkoba's texture pack boosts my fps by 2 when I use it. (Note that my average fps is 10 without it). So it's all about finding that texture pack you're computer loves.

Lushcraft 8x8 - 8x Pack

Do - Defrag your hard drive!!

Spoiler

Over time the files on a hard drive will become fragmented, which is exactly like what it sounds like, they just spread around your hard drive like wayward ants. A simple run of the Defrag tool on your computer will fix this and make your computer faster (see the quote from ThatCanadianGuy if you don't like the default defragger on windows for some reason). It's recommended to run it once a month to avoid slow downs. It depends on how much you use your computer. Heavy users need it almost everyday, light users once a year. Personally I'd say at 15% fragmentation is when you need it. Note: The more stuff you have on your hard drive the longer it will take. So it can last anywhere from an hour to an entire night.

Do - Use ReadyBoost!(windows only)

Spoiler

If you have a spare USB Storage Device (at least 2GB or more), you can dedicate it to something called 'ReadyBoost Cache'. It is used as an addition to Superfetch and prefetch. The page file mirrors itself to the readyboost drive in order to allow for faster reading of things out of the page file, however this does not actually increase the size of the page file.

To do this, simply right click the USB Drive and select ReadyBoost where you can set the amount of memory you wish to dedicate. Note: It may cause your USB device to die faster because of so much use. Don't have anything important on it just in case.

Do - Give minecraft more/less memory!

Spoiler

Launch Minecraft with less memory (yes, really). It needs maximum 256 MB and runs fine on all settings with the default texture pack. By default java allocates insane amounts of memory (1GB?) which then gets swapped to disk and the overall performance suffers a lot.

Note that launchers that use less memory should only be done with vanilla Minecraft. Vanilla means no texture pack, mods, etc, just plain Minecraft. If done with memory intense mods (humans+, mo' creatures) or a texture pack that's bigger than 16x then the FPS may be hurt, or you may run out of memory. DO NOT USE MORE MEMORY THAN YOU HAVE! If you have 1gb ram and use a 2gb launcher it will crash your game and computer.

384mb is recommended for vanilla.
512mb is recommended for mods that add a few new mobs, or use of a higher resolution texture pack. 1024mb is for many new mobs like mo creaturesif you play in browse, and super high res texture packs like x128.
2058mb is A LOT of new mobs like mo creature, humans+, pokemobs, etc. Also if you have out of memory problems. 4096 is unnecessarily high, but it is possible. These are in megabytes so 1024 is a gigabyte of ram. Adding more memory than default may help if you have a lot of spare RAM.

All OS's

Spoiler

These launchers can be used to limit memory and also install mods easily, set width and height when opening, etc.
SK's Launcher - http://www.minecraft...mc-open-source/
Magic Launcher- http://www.minecraft...s-options-news/

Windows

Spoiler

You can make a launcher youself. Use JMC17's method to edit your client to launch with less(or more) memory. MUCH safer than using a bat file. This is how to make every java applet launch with the same memory. So use this if you play in browser. Alternatively use this method

Spoiler

1) Install the proper version of Java (64/32 bits OS) via java.com
2) Go to control panel -> System -> Advanced System Settings
3) Click Environmental Variables
4) Click New and type:
(EXACTLY everything after the : and Include dashes/underscores etc.)
1st box: _JAVA_OPTIONS
2nd box:  -Xmx1g -Xms1g
5) Click Ok, done

F3 in your game and memory should in top right screen is double!
Using M or mb should work for megabytes

This is how to do it with a .bat file if you wish to do so.

Spoiler

(Note: this may work perfectly for some, but odd for others. For some it may not allow multiplayer, for some it will say you're playing an unlicensed version, and for some it just won't work. USE AT YOUR OWN RISK! One person is know getting an error that the cache file cannot be created.) I found this in the OptiFog post and it helped many including myself.

start javaw -Xmx256M -server -Xbash -Djava.library.path=bin/natives -cp bin/minecraft.jar;bin/jinput.jar;bin/lwjgl.jar;bin/lwjgl_util.jar net.minecraft.client.Minecraft username password

1. Copy and paste into notepad.
2.Replace username with your name and password with your password.
3.Save as Minecraft.bat, and put it into the .minecraft folder, which is found by going to start-&--#62;run and typing "%appdata%" without the quotes. It may be in the roaming folder.
4.Create a shortcut to the .bat file, place the shortcut in the desktop, and now you have your own custom launcher.
-Xms is the allocated amount to launch with, and -Xmx is the total RAM, change the values to ones that suit you
Setting Xmx and Xms's value to the same will always keep a fixed RAM allocation, which can avoid slowdowns in-game.
You can change the icon by right-clicking on it, clicking properties, and click the change icon button. You won't see the tumblr news but eh I say it's worth it for the fps boost and the overall system boost.

Alternative bat files:

"C:\Program Files (x86)\Java\jre6\bin\javaw.exe" -Xmx256M -server -Djava.library.path=bin/natives -cp bin/minecraft.jar;bin/jinput.jar;bin/lwjgl.jar;bin/lwjgl_util.jar net.minecraft.client.Minecraft Username Password 

Same as instructions as above.

java -Xmx256M -Xms256M -server -Xbash -jar minecraft.exe

Place where ever minecraft.exe is located.

Mac OS X

CapnCrabbes topic
Locate your minecraft.app, mine was in my apps folder
-Right click and select 'Show Package Contents'
-A new finder window has opened, now go into the /contents directory and locate the info.plist file
-Open it in textedit or any other text editing software
-scroll down to the line that says &--#60;string&--#62;-Xms512M -Xmx1024M&--#60;/string&--#62;
-This is the default allocation, -Xms is the allocated amount to launch with, and -Xmx is the total RAM, change the values to ones that suit you.
Setting Xmx and Xms's value to the same will always keep a fixed RAM allocation, which can avoid slowdowns in-game.

Linux

Spoiler

Right-click on desktop and create a new launcher, name it Minecraft and in the command put:

java -Xmx****M -Xms****M -cp /home/USERNAME/minecraft.jar net.minecraft.LauncherFrame

Right-click on the desktop and create a new launcher, name it Minecraft and place the code in the command. Just direct where your minecraft.jar(the launcher, not the game files) and there you go.
Replace USERNAME with your profile name if you're going to have minecraft.jar in your main profile folder.
Where **** is the amount of RAM, in megabytes, to allocate.
Setting Xmx and Xms's value to the same will always keep a fixed RAM allocation, which can avoid slowdowns in-game.
-Xms is the allocated amount to launch with, and -Xmx is the total RAM, change the values to ones that suit you.
Bonus: How to make it look pretty.
Open minecraft.jar(again launcher) and go to net&--#62;minecraft&--#62;favicon.png and extract it to where ever.
Click on the little keyboard with spring to change the icon image, locate the extracted favicon, then you can keep Minecraft in the launcher and it will look beautiful!

Do - Update LWJGL!

Spoiler

If you have Linux and are playing Minecraft you MUST to update LWJGL. What it does is handle the graphics, sound, and input. While windows, and possibly mac, users don't might not need it, Linux does. But even if you have windows or mac it is highly recommended you update, as there may be a performance boost and bug fixes. Here is how to update it. When updated the game should have less input problems, like keys getting stuck. Sound problems, like sound randomly disappearing. And graphics problems, such as some artifacts.

Do - Disable indexing services on Windows XP!

Spoiler

By default Windows XP indexes files on your hard drive and stores them in memory to speed up its' built-in search. But if you rarely use Windows search, turn off indexing to free up memory and CPU horsepower for the files and applications you actually do use.

Do - Download the newest Java.

Spoiler

If you already have Java then update. Each JRE (Java runtime environment) is usually better than the last since they fix bugs and improve efficiency. Note: There is a very slight chance it can hurt FPS. Google on how to downgrade back to the Java version you had if this happens.

Do - Mod your Minecraft.

Spoiler

Note: If you mod Minecraft you will only be able to play with minecraft.exe. You will not be able to play in-browser, you will only get a black screen if you try to do so. Also delete Meta-Inf if you do decide to mod it. Meta-inf lists all of the files in the program (minecraft). If one is missing, or is changed, it aborts the loading of the program. It's a good checker to make sure your game's not corrupted, but if you're modding its gotta go. (PS mods also work on Apple and Linux.)

• First of all you need a file archiver/compressor. I recommend 7-Zip. It's free and tiny (1.5 MBs). You could use WinRAR or WinZip, but those you only get a month or so trial, then you have to buy it. P.S. You extract .rar files using 7-zip.

• OptiFine HD(formerly OptiFog) boosts fps and makes fog look better. First off it now includes optimine, which was another fps boosting mod that has been discontinued. You can also select a "load far" option and "preload chunks" to get rid of lag spikes while walking. Also it includes files to play with hd texture packs so mcpatcher is no longer needed. And you can control how often the game auto-saves, which by default is every 2 seconds which causes the LagSpikeOfDeath. FPS doubling is common.

• Get rid of those clouds! If you cannot use optifine for whatever reason.

There is a transparent image there. Follow the same instructions as to install optifine but go into the environment folder and drag it into there. Or if you use a texture pack go to your texture pack, then go to your environment then change the cloud texture to this.

• Coros mods currently outdated. I'll ask him to update them.
  Spoiler

  Coros mods. The 2 we want are Smooth Rain, which changes the rain from actual rain to particles on your screen. This GREATLY increases FPS during storms. Also Menu FPS Fix, which gets rid of the panoramic picture in the main screen (if you don't wanna get rid of it don't install the sf.class) and also stops trying to get max fps when the game is paused so the game doesn't hog CPU.

Note: As with any mod you must check if these use any of the same classes of any other mods you use. But optifog is compatible with ModLoader, SinglePlayerCommands, TooManyItems, PlasticCraft, CJB's Modpack, Zan's Minimap and many other. Just install optifog after installing all these others.[/indent]

---The following are all possible ways to fix lag. But some have reported reduced FPS after this. Be sure you always have a way to revert back if it decreases FPS.---

Possibly - Play offline!

Spoiler

Supposedly playing offline increases fps. Most likely it would be stopping internet based programs from running and using ram/cpu. Easily testable so just try it.

Possibly - Change minecraft's screen size

Spoiler

For some people playing on full screen will boos FPS. This is because when it's on full screen your computer gives Minecraft priority over other windows. F11 on windows puts it into full screen mode.

For other doing the opposite and making minecraft smaller will boost fps.
I have found somthing that has helped a little. went from 12 FPS to 22. right click minecraft, go to properties and go to compatibility. i checked the 640x480 box.

Possibly - Set javaw.exe priority to high.

Spoiler

This may or may not work. Many people suggest this and there is a possibility it helps. Hold the buttons ctrl and alt, and while doing that press delete to bring up task manager. Then go to the processes tab and look for javaw.exe. Right click and set priority to high. This can cause instability and cause minecraft to freeze, but you should try it to see if it helps.

Possibly - Set windows to best performance.

Spoiler

Control Panel\System and Security\System On he left side, there will be "Advanced System Settings" Click it. Go to advanced tab, and to performance, then press settings. Then press the Option "Adjust for best performance" Click apply then ok.

For Windows 7 and I think vista watch this http://www.youtube.c...player_embedded

Possibly - Download JRE7, the beta version of the new java.

Spoiler

The new beta java runs smoother and boosts Minecraft's performance for most people. This is a beta, hence experimental. There may be stability issues, and some have reduced performance. I highly recommend trying though it seems to help many people.

Possibly - Use Ramdisk if you have 2 gigabytes or more of ram.

Spoiler

If you have less than 2 gigabytes may not have enough memory to run Minecraft very well, and will decrease FPS. This will boost fps a little, but will make chunks load a lot faster.

Ramdisk

Command: mklink /j %appdata%\.minecraft K:\

PLEASE LISTEN TO THE VIDEO CAREFULLY

Read the comments for related issues or google, or post a comment. Enjoy.
Note: After you put all your settings in RAMDisk don't forget to click Start RAMDisk or it won't show up in Disk Management.

Possibly - Update your graphics driver.

Spoiler

I highly recommend you are somewhat good with computers for this part. Your graphics card is what generates images onto the screen. A driver is what allows software to interact with the hardware. If there is a newer version of it then it should work better. Click here to see how to check driver version in Windows. In Windows 7 the device manager is found by going to control panel->Hardware and Sound and under Devices and Printer is device manager. Then go on your computer maker's or graphics card's makers website to check the newest version. If you need to update do so. This may or may not make a difference, but it you want to have a whack at it go ahead. This is something that you should only done if you can troubleshoot computer problems as this may have undesired effects. You can also google or youtube how to update your graphics driver to make sure you don't mess up. Be forewarned, a new graphics driver is not guaranteed to boost fps.
If you want to get really technical you can buy a new graphics card. You can have a borderline crap computer but a really good graphics card it will run smoothly. This is why even the fastest computers can lag, because the graphics card is terrible. Of course this is something that should only be done if you know how to take apart and rebuild a computer.

Possibly - Follow these steps posted by Lost-Ninja.
Note: Only if you have 2 or more hard drives. You MUST make sure it is in fact a second hard drive and not a partition, other wise this won't do anything. I don't know if this is only for 64 bit or for 32 bit as well, if you want to try go ahead.

Spoiler

If you have more than one physical HDD (if you only have one (eg a laptop) ignore this), follow these instructions to copy your minecraft installation onto a 2ndary drive. This may improve performance.
1)Find your minecraft install. Default is: C:\Users\&--#60;user name=""&--#62;\AppData\Roaming\.minecraft
2)On the other HDD make a new directory called Minecraft. eg D:\Minecraft.
3)In that directory create two more directories one called bin and the other called data. So:
D:\Minecraft\bin
D:\Minecraft\data
4)Copy the minecraft.exe that you use to launch the game into the bin directory.
5)Copy the entirety of the C:\Users\&--#60;user name=""&--#62;\AppData\Roaming\.minecraft into the data directory so that it looks something like: d:\Minecraft\data\.minecraft\ ((Make sure you copy rather than move as this will give you a backup in case of failure.))
6)Create a .bat file that contains the following text: (To create a .bat file you need to create a text file then change the extension from .txt to .bat.)

set APPDATA=d:\Minecraft\data
bin\minecraft.exe


7)Update any shortcuts you use to launch the game to point to this .bat file.

If you have x64 OS you should get a better FPS/performance running a x64 JRE.

Some evidence suggests that using the JDK also boosts performance (does for me and I have heard other people have had some success with it. (This is the Java Development Kit, it includes the JRE (the normal Java most people have) and shouldn't make things slower but might improve things.

However while the above have all helped me eke out a fair amount of FPS and remove an awful lot of chug they may not work for everyone.

Possibly - Install a Linux OS!

Spoiler

Any Linux will do, but I would suggest Linux Mint or Ubuntu as they are user friendly and easy for people who are not used to linux. Of course I don't mean to replace your current OS, but rather to install it alongside it (Most likely windows). In fact Ubuntu has a program called Wubi that installs Ubuntu through windows and you can manage Ubuntu in windows like any other program. The reasoning is that Linux doesn't have a bunch of background programs to hog memory. The same could possibly be achieved by wiping your entire windows install and starting fresh (though why anyone would do that just to boost fps in a game is beyond me personally). Also the main reason for using Ubuntu over just a clean XP install, on these ancient XP boxes with Intel graphics, is that substantial driver work has been done beyond that seen on the Windows platform, this can result in faster 3d performance for old Intel graphics. Modern Nvidia/AMD hardware will not see a benefit from this.

(¯`·._.·[ Speeding Up Your PC ]·._.·´¯)

When it comes to PC optimization, there are many things you can do to get more speed from your PC. In this section, I'll explain various things you can do to get more speed from your PC, and in turn, more playability from your games (games in general, not just Minecraft).

The original version of this guide was essentially just PC optimization, and it was huge in size. I'm going to try to trim the fat and keep things small and simple, probably using quote tags to section things off.

Useful programs

● GameBooster from IOBit.com[Please read the second question in FAQ below! - IronWaffle]
● CCleaner from Piriform.com
● Glary Utilities from GlaryUtilities.com
● Defraggler from Piriform.com
● PCDecrapifier from PCDecrapifier.com
● MyDefrag from MyDefrag.com (Thanks Cipher_Nemo)
● UltraDefrag from UltraDefrag.Sourceforge.net (Thanks Cipher_Nemo)

General Tips


● Shut down unnecessary processes that don't need to be running while you play a game (GameBooster does this very easily with no risk of screwing your computer up)

● Run the disk defragmenter! Files get fragmented over time and can really slow your system down.

FAQ

Q. I get a blackscreen after I modded minecraft, wtf dude?

Spoiler

A. You most likely forgot to delete meta-inf in minecraft.jar, this folder checks if your minecraft.jar folder has been changed, if so it blocks launching. If meta-inf is deleted then there's 3 possibilities.

1. If you have several mods it is possible they're conflicting (see mod your minecraft's note for more details).

2. You installed it wrong, in which case simply force update minecraft and try installing again

3. There something weird going on, in which case you should ask the forums for help. Ubuntu for instance has a problem in 1.8 where installing modloader will put modloader.class in the java folder in minecraft.jar, here it's solved simply by cutting and pasting from the folder to the main jar section.

Q. I heard of a program called gamebooster that turns off non-critical programs in the background, should I use that?

Spoiler

A. I wouldn't. It turns out that the company stole malware definitions from Malwarebytes' database and proprietary intellectual property and incorporated into their own software (Link for proof). This is a serious ethical issue. While I don't think gamebooster is dangerous I won't rule it out from people who steal. I highly advise against it as it really doesn't give you that much back, but in the end using it is your choice. I was originally not going to include GameBooster in the quote but left it in for those who still want to try it.

Q. I can play fine for 30 minutes or even an hour but then Minecraft lags like crazy no matter what I do, why?

Spoiler

A. You may need to dust your computer. It may be something else that's causing this but a thick layer of dust will also do this. Overtime your computer gets dusty on the inside. The dust acts like a blanket and keeps heat in. Make sure not to touch the microchips as the smallest amount of static can fry it. Wikihow instructions. Every computer opens differently, this is especially true for laptops. Read your manual or google how to open your specific machine.

Q. I have a Nvidia/ATI card and everything else runs fine except Minecraft. Huh?

Spoiler

Minecraft, for whatever reason, will run off your integrated graphics card instead of the nvidia card. It's easy to fix this Right click on desktop and click "Nvidia control panel" It will literally shoot up from 2 to 200 FPS. Thanks to BrianTheSwat here's an alternative way to get to your settings. Also donkeypong pointed out that you may be able to right-click minecraft.exe and go to "run with graphics processor" and select the Nvidia card. If anyone knows how to add programs to an ATI card PLEASE tell me. I've searched and found nothing. Here's a video on how to do so if you got confused.

Spoiler

http://www.youtube.c...h?v=d_0Cmd7iLi4

Q. Do you have any other resources to help me?

Spoiler

The Gamer's Graphics & Display Settings Guide. I have to admit I had a tl;dr attitude when I saw this, but from the first 2 pages its seems to really be use full. It goes really in depth as two what somethings are like refresh rate, fps, response time, etc. I don't know if it actually tells on how to help things, most likely it does. This isn't just minecraft, but other games as well. How to Get Rid of Lag. This isn't just minecraft, but other games as well.

Q. How do I open my .minecraft folder?

Spoiler

A. For windows hit run and type in %appdata%, and it will either be there or in the Roaming folder. For other systems, google "how to open .minecraft folder in X" where X is your system.

This is mine on single player. Before: Regular day - 5 FPS (Yes my computer is a netbook, so it's that bad) Good day - 9 FPS Biggest FPS spike seen - 14 After: Regular day- 12 Fps Good Day - 16 Fps Biggest FPS spike seen - 27 Optifine and linux are what boost mine the most.

Don't - Set javaw.exe priority to high. Many people suggest this but I have never seen this work and just causes a bunch of other negative side effects. If Minecraft really needs the extra memory it will get it from the computer. Just dumping memory into it won't help, and takes away from other programs, slowing them down and possibly even slowing down your computer, which will slow down minecraft, which will completely defeat the purpose of giving it more memory. And it can cause instability and cause Minecraft to crash.

Considering Minecraft is CPU intensive,I'd say it needs all the extra memory it can get.
Priority only changes how 'often' for want of a better word, that the computer will provide additional memory/allow extra cpu usage to go to Minecraft.

Critical System Processes are high by default, but very few processes that your computer will run in the background use a lot of CPU. Most are normal priority by default.

It will not cause instability in the system by increasing the priority of a program/process that you know needs a lot of CPU devoted to it.

Although in the other extreme, setting a program that uses a lot of memory to low priority, will cause lots of lag and slowdown, and just for the program itself. If you did this with Minecraft, I guarantee you would crash a lot more, and this would cause instability.

High priority on CPU intensive programs is the right way to go about reducing problems. Sure, anything in the background will run sluggishly if it's starved of memory, e.g internet browsers. This is why you shouldn't increase priorities when you have other programs running that also need an adequate allocation of memory.

If you're going to be using other programs while playing minecraft, then don't increase Minecraft's priority if you want everything else to run as smoothly.


I should say that reducing the priority of recording programs while increasing priority on Minecraft works perfectly fine. programs such as Fraps 'technically' run in the background. This will boost FPS while recording.

If you have a good computer that runs Minecraft fine, then priority won't do much, if anything for you.

If you have a poor computer, priority will often allow Minecraft to run smoother.

I also remember being pretty much the first person to point out that altering priority did improver performance.. eh it was sometime last year. I dunno if I could dig up a thread that old.

This I can argue against. When I try doing this on my netbook it doesn't help at all, then it freezes minecraft if I pause it.

That's on your computer. Not anyone has the same PC as you do.

Your guide is flawed in multiple ways:

1. You tell people what they can and can't do...you probably want to change that into "try for yourself, see if it has any positive effect".
2. You based the whole guide on your point of view about what should be done to speed up Minecraft.
3. I would suggest Java 7 only to people who want to experiment with Minecraft and know what they're doing, because it's a premature BETA. Can't confirm that Java 7 has any benefits on FPS over Java 6.25
4. How should modding your game, in general, speed up Minecraft?
5. Having other programms in the background running shouldn't be a problem, unless you have 20 programms running at the same time and/or use an ancient system. In fact, I wouldn't recommend to anyone turning of their Antivirus Software, which is running in the background, when playing the game browser based.
6. You don't need to be a technical wizard to change or deinstall your GPU drivers or any other hardware related drivers.
7. If Minecraft starts to lag after 30 minutes, then this is not necessarily related to the overheating of your hardware.

However, it's correct what you said about Optimine/-fog, allocating more memory to Java and that Gamebooster sucks elephant balls.

The video seems to be a holy grail if it does what this guy in the video promises. We'll see if this gets rid of the lag spike I'm experiecing. If so, you get a cookie for showing me the video.

You make a valid argument.
1. I'll add the try it out note at the top.
2. If it works for me it'll work for others, what I didn't think about was how many it might actually help. So I'll fix some things.
3. I'll point out this is very experimental.
4. By modding I mean only adding optifog.
5. Which is why took out the game booster one. I said having programs open, not in the background, will slow it down.
6. I made sure to point is this is possibly dangerous because if a person who knows very little about their computer decides to replace their driver and something goes wrong they'll be completely lost.
7. No not necessarily but possibility. I'll point that out too.

I highly appreciate your criticism because I want this to be the best guide to help the most people. I'll fix it soon.

Is it better or does it still need work?

[ighnot]

What settings are recommended (not only within the game, but for drivers, OS stuff (like java priority, etc), and the like, if you have a really powerful computer and want the game to look its best? I have some 256x256 texture mods loaded and enough juice in this thing to run the latest triple-A titles like butter, but when it comes to seemingly simple-looking programs like this I found early that the 3-d grid nature of the world and the render limitations of Java brought my rig down a bit-- not 'to its knees' or anything, but some choppiness I really wasn't used to.

So for you people with beefy rigs, what are you running the game at? Another thing-- using F-11 to put the game at full screen is nice and all, but the graphics scale UP and don't really look BETTER, only BIGGER. Anything to be done for this? I've seen some videos on YouTube that show much more detailed textures and such, more than I've ever seen with the mods I'm running, but I don't have a clue what they DID to get that look.

Any help or advice on this would be greatly appreciated.

I'm excited to think what this game's going to be like when it's officially released.

Um I did all the steps you said for the start javaw -Xmx256M -Djava.library.path=bin/natives -cp bin/minecraft.jar;bin/jinput.jar;bin/lwjgl.jar;bin/lwjgl_util.jar net.minecraft.client.Minecraft username password

But when I try to use it with the shortcut I get... is Windows cannot find "javaw"

Are you sure you typed in your username and password right? And the .bat file is in the .minecraft folder along with the bin and resources folder?

Yeah I got all my username stuff right and I put it in my .minecraft folder. But Do i have to put it in the bin and resource folders too? Or do I have to make it run as administrator O.o?

Everything should be running smoothly. What operating system do you have? And do you know what version of java do you have?

Um All I remember is I have windows vista and no idea what java version =/. Says something on the one of the file names jre1.6.0._02 =/ might be old lol

It should work, this is strange. The current Java is 1.6.26. I don't think updating java would work. Keep trying, sometimes the .bat file is stubborn when trying to start it the first time.

Wierd I fixed i by making it a zip file then placing it in .minecraft then using jzip to run the batch while still in the zip file.
but then if i try to play multi-player I get bad login

That is so strange... idk if the username and password is case sensitive... I'll add a note that doing the custom launcher may be buggy for some people

the video was a bit off topic at times but other wise a pretty good list.

If you have more than one physical HDD (if you only have one (eg a laptop) ignore this), follow these instructions to copy your minecraft installation onto a 2ndary drive. This may improve performance.
1)Find your minecraft install. Default is: C:\Users\<user name>\AppData\Roaming\.minecraft
2)On the other HDD make a new directory called Minecraft. eg D:\Minecraft.
3)In that directory create two more directories one called bin and the other called data. So:
D:\Minecraft\bin
D:\Minecraft\data
4)Copy the minecraft.exe that you use to launch the game into the bin directory.
5)Copy the entirety of the C:\Users\<user name>\AppData\Roaming\.minecraft into the data directory so that it looks something like: d:\Minecraft\data\.minecraft\ ((Make sure you copy rather than move as this will give you a backup in case of failure.))
6)Create a .bat file that contains the following text: (To create a .bat file you need to create a text file then change the extension from .txt to .bat.)

set APPDATA=d:\Minecraft\data
bin\minecraft.exe

7)Update any shortcuts you use to launch the game to point to this .bat file.

If you have x64 OS you should get a better FPS/performance running a x64 JRE.

Some evidence suggests that using the JDK also boosts performance (does for me and I have heard other people have had some success with it. (This is the Java Development Kit, it includes the JRE (the normal Java most people have) and shouldn't make things slower but might improve things.

I haven't had any luck getting Optimine & Optifog working with my mods (missing textures) however installing the Lag Spikes of Death patch has made a huge impact on my framerates. Get it here it's a little below the main Optimine/Optifog downloads by the donate button. And modifies the fb.class file. (I think it does something to stop MC saving every 5 seconds but am not sure...)

However while the above have all helped me eke out a fair amount of FPS and remove an awful lot of chug they may not work for everyone.

Nice tutorial. I'll include this in the guide. Does this work for 64bit only or 32 bit as well. Doing the tutorial and using jdk instead of jre. And does jdk use more power then jre. Also do you know if using the beta jdk7 runs the game smoother than jdk6.
