Crusader Kings 2 crashes after a few minutes on lower end systems and a bit later on high end systems. with this error in the debugrun err:d3d:buffer_sync_apple >>>>>>>>>>>>>>>>> GL_OUT_OF_MEMORY (0x505) from glBufferDataARB @ buffer.c / 607 wine: Unhandled page fault on read access to 0x00000000 at address 0x539239b4 (thread 0009), starting debugger... Whole debugrun will be in attachments. Happens on osx lion and Snowleopard systems.
For me on my AMD Radeon 6770M graphicscard with 512mb, I could play at least 30 minutes.
