I encountered a GPU freeze when zooming in and out from the map often.
The game freezes up for a few seconds, then VPU Recover from ATI says that the gfx card did no longer respond so it has been resetted.
Without VPU Recover, this would be a crash bug.
I am using Win XP 32bit SP3, gfx card ATI Radeon HD 3870 (Sapphire Ultimate Edition)
