Also to add on to this comment by Dodge sp everyone major modder including the forge team is ed at you right now.

Here is the most recent comment towards you: "If you need to delete meta-inf to INSTALL YOUR MOD in 1.6, you're DOING IT WRONG. Plain and simple. It is NEVER necessary anymore.."

I'm just saying from a mod players point of view with using FTB packs and just forge itself. All your "special" features like connected textures are from mcpatcher and can be installed from that and other things like fps improvents are being done good enough from forge and mojang there is no need for this mod anymore. It is a nice mod but you are starting to go down the wrong path and if you manage to keep going on that path and get enough people mad at you your mod is dead.

alright, then can you please point me towards a mod that has most, if not all, the same functions as Optifine?

However, no such mod exists that does any of the functions that optifine does.

Here's the problem with that: I STILL can't run minecraft without optifine. I realize that Mojang wants to make optifine useless in the long run, but they're nowhere near that point for those of us who have weaker computers.

The 1.6.2_OptiFine folder isn't showing up for me in the launcher why isn't it?

currently MCPatcher and Forge are not compatible. Its NEVER been that way, until the 1.6.2. So, right now Optifine is the only way to obtain all those special texture features, and use forge.

Its obvious an end game is going to come where something will have to give from one of the authors. But it makes me a bit angry that im going to be forced to choose between nice/proper graphics, and certain mods.

and, FWIW. Im currently using Optifine and forge 786 using the parameter flag installation via MagicLauncher. Thats not editing any sort of Jar file in any way shape or form. So im not sure the message is as targeted as you implied.

Quote from DrFantasmo2012

It's because his work-around only works with the default texturepack because he moved textures to a different location. "/textures/itemsbed.png". Normal textures like your texturepack loads from "/textures/items/bed.png" and since optifine is bugged and tries to load from "/textures/itemsbed.png" it won't find your texturepack and will default back to his work-around.

If you would like to use a texturepack i would recommend my fix which modifies the class file and changes optifine to load from "/textures/itemsbed.png" to "/textures/items/bed.png" allowing texturepacks to load correctly.

ugh, I wait a week for it to come out for this to happen.

Read the op, then redownload the 1.6.2 A2 version.

@sp614x: OptiFine_1.6.2_HD_U_A2 with "Chunk Loading: Multi-Core" makes for incredibly smooth performance. Virtually all World Tick related stutters and most chunk loading related hitches are gone. Thank you so much for making this preview available early!

Place that file into: /name of resourcepack/assets/minecraft/textures/misc
This should work

what file? its just a weird text... help please, cant get texture packs to run on magic launcher with optifine on

Hey, I have Biomes O' Plenty installed and I am getting those purple black checkered blocks on biomes o plenty related blocks like mud, new flowers, magic wood, etc. If something could be done to fix this that was awesome. Hope the official release is soon

Just wondering if this is compatible with 1.6.1 just because of the minor bug fixes.
yes, no?

has anyone tested the preview? does it work?

I got that too.. .but no one is helping

When using "Chunk Loading: Multi-Core" make sure to Disable "Threaded Optimization" / "OpenGL Threading" in the graphics card control panel (example). For best results disable it globally, not only for java.exe or minecraft.exe.

I suffer from the flickering when using Multi-core chunk loading. I was able to solve the flickering by disabling threaded optimization in a Java.exe profile (Nvidia drivers). My question is what, other then the flickering, could I be exposing myself to by not disabling it globally?

If there's nothing else to worry about (besides flickering) I think it would be more convenient to disable it for java.exe than a full global disable. Thoughts?

can someone please tell me where the 1.6.1 download is? The sever that I play on isn't on 1.6.2 yet, and I need 1.6.1 baddly. And optifine 1.6.2 won't work with 1.6.1, so don't ask.

Quote from Erik13

has anyone tested the preview? does it work?

I'm running a windows 7 PC, latest Java 64-bit. I've tested this preview with 1.6.2 and it works just fine for me.

Quote from Baheskey

I followed those instructions (I wasn't too sure about the installation of forge but it appeared in the magic launcher so i'm assuming that's ok, right?) and I end up with this error message:

Is this.. fixable?

Well to be honest, I have no clue what any of the error means, but I can tell you that it should be working. Here are the steps I took:
(Also, before doing this it might be a good idea to go into the versions folder inside your .minecraft folder and delete everything except for the 1.6.2 folder in there, that way nothing gets mixed up with the forge installation)

1. Download the 1.6.2 recommended forge installer and universal jar files.
2. Run the forge installer
3. Open up the vanilla minecraft launcher (so minecraft.exe, wherever you put that) and select the "Forge" profile from the dropdown box.
4. Let that run and make sure it starts correctly.
5. Open up magiclauncher and click setup
6. select the 1.6.2-Forge######" environment
7. Click the add button and find your optifine zip file and select that
8. Go to the "advanced" tab and put -Dfml.ignorePatchDiscrepancies=true in the "parameters" box.
9. Click OK and then Login and it should work.

Seems to require a lot of launchers to install with forge
