Whenever I play ftb on minecraft, java uses up like 3,000,000 K memory in the task manager and my cpu and ram are at 90-100%. I don't have any other programs open. I also only have around 20 fps while playing. My computer has 6gb of ram and an AMD Athlon II X2 250 Processor. I don't know what to do because I can't play with 20 fps. Someone help,
Java taking up too much ram
