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.
