Hi, I need help with a problem i have had for a little while now. My problem is that my minecraft will normally runs at a good 70-100 fps for like a solid 10s or 15s, then just drops to 0-10 fps instantaneously, then back up to 70.... and it just repeats. I've tried messing with the video settings (even putting them on the lowest it goes) but the problem is still there. The only mod I am currently running right now is Optifine, and it isn't helping. If someone could help I would greatly appreciate it.
