Minecraft Forums

I found a post to have optifine and forge to be compatible until it get's fixed, but it is harder to do than the normal.

Edit: ragger's suggestion is way easier and more efficient than this post.

Download and install forge.

1. Go to .minecraft/versions/ then select the folder which forge just installed
2. Open up the .jar in that folder with an archive manager
3. Delete META-INF
4. Open up the .jar file of Optifine with an archive manager and drag the contents into the .jar
5. Start the launcher and edit the Forge profile
6. Add these parameters "-Dfml.ignoreInvalidMinecraftCertificates=true -Dfml.ignorePatchDiscrepancies=true"

So... Forge #884 and #885 basically made it so that the mod got ignored (it loaded without enabling the mod) but it threw an error in the log. #886 and #991 crashes differently now... Is this something that needs fixed on the Optifine side?

OptiFine is not changed, it uses the same loading mechnism as 1.6.2. Forge 1.6.4 has been reorganized and does not load it properly now.
From the stack trace it looks like it gets loaded after the deobfuscation step, while before it was loaded before the deobfuscation which is the correct way.

i will love u if u make optfine por mcpe.

I use a Mac and Optifine makes my FPS go from 200 down to 2. I know all my friends who use Macs have the same issue. Is there a specific bug on the Mac, or do you just hate Macs, fine sir?

Yeah, on single player there shouldn't be a limit as to how far the world renders. Also take a look at post #36623 as someone gave an explanation on it.

Poster #36623 didn't appear to have the same problem as me, mine never loaded past Far, moving or not. Also the other post (36621) saying to try "Load Far", that didn't help either. However, I found a solution that did work.

There's a file in my Minecraft directory called "optionsof", I'm guessing this is the Optifine Options file? If so, then changing the Optifine view distance in game should change the view distance in this file. But for some reason it wasn't for me. I edited the file manually and saved it. When I started Minecraft, the view distance was set back to Far again but this time when I moved it to Extreme it started loading more blocks! So for some reason I guess, the options file wouldn't go beyond Far? I'm not sure what would cause this. But this is the first time I've ever gotten it to render past Far so I think what I did fixed it.

However this has created a new problem, at first the FPS starts out pretty normal for me (100ish). But after about 10 minutes of gameplay it slowly starts going downhill until the average is around 20 while walking, but drops to like .5 randomly especially when turning and walking. I'm a bit confused as to why this is happening. I mentioned my specs before but they are as follows;

Windows 7 Ultimate 64-bit
Intel i7-920 @ 2.66 GHz Turboboosted to 2.8 GHz
24GB of Corsair Platinum RAM, triple channel @ 1600 MHz
Nvidia GTX 680 Video Card

Here's a screenshot of the Windows performance monitor running side by side with Minecraft at Extreme:



It appears that Minecraft is maxing out one of the Processor's threads, but barely touching the others. I thought that Optifine was supposed to alleviate this on it's multi-core setting? I'm guessing it's just not true multi-core support? So the only way to fix this would be a better processor/overclock?

Let me know if you guys have any ideas. Thanks.

Please add cit, custom fishing rod and lead lines support
And ctm support for bed, iron bars and brewing stand

Also, the light version will ever support forge?

I have a Mac with Optifine installed along with multiple mods(Inventory Tweaks, Dynamic Lighting, small mods like those...), and Optifine helps(at least doesn't harm it) the frame rate considerably. May I ask what kind of mac do you have?

Yes. That confirms what they said over on the forge forums. I think this is being passed to your court though.

If the FPS is dropping when turning around, then the GPU is most probably running out of graphics memory and have to swap to the slower system memory. The visible chunks (in front of the player) are in the graphics memory, the invisible chunks (behind the player) are swapped to the system memory. When turning around the GPU has to load the prevously invisible chunks in the graphics memory in order to show them and this causes a short FPS drop.

OptiFine can only be loaded before the deobfuscation as it uses obfuscated classes.
The solution is to restore the FML 1.6.2 functionality.
Updating OptiFine to use unobfuscated classes is not possible as it also has to run without Forge.

The Light version will never support Forge.
The Forge support is quite complex and the Light edition is designed to only add simple changes to vanilla.

Oh, ok
And what about the other thing I said?

My apologies for assuming such a harsh thing...

There isn't an error log... It just makes my FPS go down to 2. It doesn't crash my game or anything. Do you want the game log?

With Forge 896 Minecraft finally loads again with Optifine in the mods folder, just to crash then:

Without Optifine Forge 896 starts, so is it a problem of optifine or still forge?
