--- Comment #5 from Ken Thomases ken@codeweavers.com --- Thanks. It appears that you collected that log with the VideoMemorySize=512 setting in place, which avoids the crash. I need a log of the crashing case, without that registry setting.
The Mac driver WGL_WINE_query_renderer code detected 1536MB VRAM, which isn't too unreasonable. Out of curiosity, what does About This Mac show on the Displays tab?
