Hello I've been trying for months to make my FPS go up I've installed optifine but nothing but I think it has some thing to do with java 64 bit. Prior to installing java 64 bit I played on a modpack using 1 GB just fine then once I installed java 64 bit I could play it I keep my GB at 3 and I Have a 64 bit operating system. Please help and don't say uninstall and reinstall I've tried, thanks.
