The game runs just fine. I built myself a house, explored a village, and cut down some trees. However, any time new chunks are loaded, Minecraft has a chance of crashing. This happens any time I walk away from my house in one direction for more than 1 minute. It crashes regardless of RAM setting (tested on both 1GB and 4GB). This is the FTB beta mod pack with added Optifine. This problem does not occur on my superflat test world.
Code:
Minecraft has crashed!
