I have had almost the exact same problem. Around 5 to 15 minutes into playing Survival I have extreme lag, down to 0 FPS and 0 Chunks, and I cannot continue playing. Exiting the game altogether fixes the problem for the moment, but then it pops up again later. Exiting out to main menu does not fix the lag. Interestingly it didn't happen while I was building my castle, but happens all other times. Started happening with 1.4.4 update and continued to 1.4.5 My comp stats are the same as Tyler's except I have Invidia GEforce GTX 260 M. All drivers reportedly up to date. I have it happens at some pretty inoppurtune moments, i have died a few times when a creeper shows up behind me and all of a sudden it lags. Yet I still play this game. Cause its awesome. Please please help.
