--- Comment #19 from MirceaKitsune sonichedgehog_hyperblast00@yahoo.com --- The freeze still happens with the Performance Enhance BIOS setting turned off, the crash is not caused by my overclocking settings. It took 2 hours of playing Minecraft in a row for it to occur again.
I noticed an important clue: In the case of Minecraft, the system only seems to crash after mobs have loaded into view. If I only explore a world where no entities spawn (be it full of voxel geometry), the freeze has never happened thus far. This made me realize that all engines I noticed the freeze with have one thing in common: A skeletal mesh is loaded into view. Could this be an issue related to animated models by chance?
Note that I don't suspect Vertex Buffer Objects to be a cause: I once turned off VBO in Minecraft, restarted the game, and still got a system freeze.
