I've been able to play Minecraft at a solid 30 FPS forever, and now it started lagging. The weird part is that it's not the framerate. It says I have 30 FPS, but my actual CLIENT is lagging. On the main menu, It will go, skip and go and skip and it's REALLY frustrating. I've tried OptiFine, but that wouldn't work since it's the client thats lagging. Any help would be appreciated
