I’ve tried all kinds of tricks to increase my FPS(frames per second) in Minecraft and haven’t really found much that helps. I currently use Optifine Ultra and have tried all kinds of settings to increase my FPS. We play the Direwolf20 mod pack for Feed the Beast and it alone will almost cut your regular Minecraft FPS in half. So last night I was determined to find a solution and I ran across this video. This has been the solution to my problems and I cant believe it was so simple. I decreased the memory that Minecraft runs at to 1gb of ram and increased Java Runtime to 3gb of ram and my FPS has doubled if not tripled in some cases. I hope this helps you as much as it has me because frame rate spikes were starting to really become an issue for me. And as always if this helps you out show some love to the You-tuber and a least like the video.
