(In reply to comment #14)
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.
After removing the line containing this extension I get the behaviour of wine version 0.9.47 to 0.9.49. The whole window is a solid color and it changes when changing menus (via shorcut keys ofcourse), which means it most likely points to a single pixel somewhere.
