Problem adding optifine

[merciless571]

I tried to add optifine because I get lots of lag and only get around 1-10 fps, so I first added it to the jar and when I tried to launch the mod pack, it worked at first and got onto the mojang screen but after around 40 seconds it closes and takes me back to the launcher. I then redownloaded the modpack and added optifine to the mods folder and the same thing happened. Is there anyway I can add optifine to the modpack so I can play it without lagging?

Did you download the optifine you needed, This one works for me : http://optifine.net/adloadx.php?f=OptiFine_1.6.4_HD_C6.jar.

And also try deleting Tropicraft and the weather mod, it greatly improves your fps.

Did you put optifine in the mods folder or in the jar?

[CoolCC]

You put it in the mods folder.

Does this work for 1.7.2?

I've tried that version of optifine with the newest B Team update but for some reason the server crashes now. The server works if I take optifine out though... I have the crash report if needed.

The server doesn't use optifine. Optifine is a client side mod.

The mod pack is only at 1.6.4

Optifine does work for 1.7.2, however you need to download the correct version for 1.7.2. The one provided in this thread is for 1.6.4
