--- Comment #3 from Rico kgbricola@web.de 2012-08-07 05:01:01 CDT --- What's the exact version for COD4? There seem to be reports in the appdb where that game works fine ( see http://appdb.winehq.org/objectManager.php?sClass=application&iId=5934 ), even with pretty similar hardware. You may run a regression test to find the patch which broke it (http://wiki.winehq.org/RegressionTesting/). Do you have any special settings in COD4 that may trigger the problem?
@nomessage89 What's your OS? What's your gpu driver version? The 3700+ is a single core cpu? Does the demo have the same problem?
