--- Comment #26 from DL taedium_vitae@eml.cc 2009-02-24 22:59:35 --- Okay, I tried the SRGB hack from the Warhammer Online appdb page and applied it against wine 1.1.15.It gives quite a nice performance boost compared to wine-1.1.15 for left4dead,portal and hl2 although the fps increase is not as great as the increase with hl2 + wine-git.Here are some examples of approximate average FPS with HL2: wine-1.1.15 = 15-35 fps wine-1.1.15 + remove srgb reload hack = 18-50fps wine-git = 60-100 fps
Left4Dead: wine-1.1.15 = 12-20 fps wine-1.1.15 + remove srgb reload hack = 25-50fps wine-git = 10-22 fps
As you can see, the git patches improve HL2 greatly but stay about the same with left4dead.With the srgb patch + wine 1.1.15 HL2 improves somewhat and left4dead gets a quite decent speed increase (portal has similar results).
The newer patch is obviously the better solution provided that it can be made to work properly with left4dead and portal, as it gives a much greater speed increase.
I've attached a version of the warhammer srgb patch that has the vertex blending portion removed and applies cleanly against wine 1.1.15.All it does is comment out the SRGB reload section.
