--- Comment #11 from Roderick Colenbrander thunderbird2k@gmail.com 2009-11-19 06:38:20 --- This bug was about a particular type of crash in c&c3. The issue you are seeing is something else and would require a new bug. I don't think your issue is a Wine bug though. Except for Nvidia their drivers (and lately also AMD their own drivers) modern games don't work well on other e.g. open source display drivers. They don't implement support all modern 3D features and the performance isn't that great. It sounds like you are using a radeon >=9500 card (r300) and it might be hitting its limits according to the crash. If you can I recommend to use an Nvidia card.
