I installed 13.10 last night on a Dell Precision M6500 and I was amazed that I could get ~50 FPS, but then after about 5 minutes, it took a sudden drop to about 2 FPS. This happens every time and framerate will not go back up unless I kill all java processes and restart Minecraft. How can I prevent this frame drop?

Have you tried to monitor your system while Minecraft is running? I imagine Minecraft is very memory intensive. –  Ross Mar 3 '14 at 21:58
Yeah, I ran htop while I was playing, and it just showed basically all resources full, even if it was running fine 5 minutes ago –  Zachary Alfakir Mar 4 '14 at 0:08
