--- Comment #14 from Roderick Colenbrander thunderbird2k@gmx.net 2007-12-24 12:18:00 --- Can you edit dlls/wined3d/directx.c: Right at the beginning, there is a table containing opengl extensions. Can you comment out or remove the line GL_ARB_texture_rectangle, recompile and see if that makes the game fast?
Not too long ago this extension got added to wine but on some cards it might be emulated.
