I've downloaded and installed every single version of Optifine for 1.12.2 Forge. Each one of them crashed upon boot. I imagine the log would be too large to fit in a standard pastebin, and I wouldn't even know where to find the exact logs. I really would want this in my modded Minecraft because I know it would fit visually. Please advise.

Use the latest.log from /.minecraft/logs/

and add it with paste.ubuntu.com

Hi there,

pretty easy install. Used a fresh Minecraft install 1.16.5 and started it once (for the downloads). Executed the Optifine installer successfully. When I run the launcher, I can start Optifine version of minecraft - but ... it looks exactly the same as the unmodified game. I don't see any difference. Do I have to activate it somehow? No idea what's wrong here :-(

Optifine does not make any changes - it adds some more settings

So check the settings or press F3 - on the left side, Optifine should be mentioned

In the video settings there is now a shaders button - with it you can change the look

Get some shaders as zip-files and put these to /.minecraft/shaderpacks/

I found a nasty bug that has not been fixed, when I put a random shaders and change from small to large screen or vice versa, the view becomes completely BLACK even if they are still in the game and I play safely if not for this bug please fix ?
my pc stats:
processor: core I3
GPU: Intel HD graphics 2500

do i need to turnoff virus scan to download it? your website whenever i wanna download 1.16.5 g8 it just detected a malicious website lead to other website and refuse to play adsfly or something it wont download it at all.

The shown url is safe - maybe it refers to the ad

Good thing I removed Avast long time ago (about their ad thing I don't remember fiasco) and optifine.net is safe. I do agree TileEntity's its maybe related to ads shown on the website.

i fixed it now i found from other thread has this similar issue all i need to do is disable avg shield and it worked out i figured it just my virus scan are just blocking it

also what do i need to fix this annoying opengl error 1284 thing? since i dont really use shader at all or any mods running just defaults running, can i just ignore in my video setting > others > hide shown error thing?

Where is 1.2.5 Optifine link?

Optifine 1.2.5:

https://optifine.net/adloadx?f=OptiFine_1.2.5_HD_U_C7.zip

Ok.......so I'm STILL unable to run Optifine & Forge together for whatever reason. I can run Optifine.....I can run Forge.....this is driving me bonkers.

Re-explaining my problem as it currently stands:

For whatever reason, I cant get Optifine to run in the same profile as Forge mods on 1.15.2; its either just Optifine or just Forge. Its not like it used to be, where I just drop Optifine into the mods folder; the one that the installer puts in the versions folder doesnt get recognized as a valid mod when I attempt to copy it into the mods folder to run on the Forge profile, and the Optifine profile doesnt have Forge attached to it.

Someone plz halp.

Make sure you are using the recommended Forge version for Optifine

So the 1.15.2 OptiFine HD U G6 version requires Forge 31.2.45

Test it with a new Game directory:

In your .minecraft-folder create a new folder "instances" - inside, create another new folder "modpack-1.15.2"

So the path is /.minecraft/instancec/modpack-1.15.2/

Install Forge 31.2.45 as usually (don't change the path, just click ok)

Start the Launcher and create a new profile at "Installations"

Choose Forge 31.2.45 as Version

At Game Directory choose the "modpack-1.15.2"-folder

Start this Profile and close the game in main menu

At /.minecraft/instances/modpack-1.15.2/ now you will find the mods-folder

Add OptiFine HD U G6 and start the Forge profile again

Now Optifine should be available (check the setting/press F3 ingame)

If not, add the latest.log from

/.minecraft/instances/modpack-1.15.2/logs/

Ok, so for whatever reason, after having ran 1.15.2 regularly again, it finally decided to install.....also I wasnt aware that OptiFine no longer shows up on the 'mods loaded' thing on the title screen (and instead shows uo in the options menu).....so for all I know I may have actually done it successfully before w/o realizing it......MC why did you have to torture me for around 3 months..... XV

The whole thing with the different folder is what I tried to do initially.....maybe it just wanted said folder to be within the .minecraft folder (it was on the D drive instead)?

Generally, Optifine isn't shown at the mod-list - you have to check for it ingame (Press F3)

I think I was thrown off because it shows up on the start menu when there isn''t Forge but doesn't when there is.....oi vey, I'm just glad to FINALLY get this all straight. XD

Hey everyone! I'm new to using optifine and I'm having some trouble installing it. Everywhere I look I see an install file but my optifine download comes in a .rar file and once extracted it doesn't have any install file
I downloaded version OptiFine HD U G8 for the latest 1.17 game patch from the official website Thank you!

Test it with another browser

Test it with another browser

I tried Microsoft Edge (I don't have another) and it's still a rar file.

EDIT: I see what happened! My pc was marking it to run with winrar. It did say .jar but sinmce the icon was the winrar one and the names are similar I automatically read .rar

Thanks for the help tho!
