Hi, If you have Legacy Drivers of Nvidia (96.43.05), every D3D games will return a boucle of "GL_INVALIDE_OPERATION". We can't upgrade drivers to >= 100.x.x because (e.g Ti4200) il not supported. This incrass game speed. To 'fix' it, just disable debugging log : Code: WINEDEBUG=-all I post it here, because I haven't found this issue on the web. ;) If this was already been said, please delete me post. (sorry for my bad english, I'm french) Max.
