Seems to be fixed in current git, at least with HL2, which now runs at 60+ fps instead of 20+ fps for wine-1.1.15.Left4Dead doesn't seem to have any noticeable performance increase in between current git and wine-1.1.15; both get between 20-38fps or so with low settings.
That's because of stefand's recent commit: http://source.winehq.org/git/wine.git/?a=commit;h=c585b4de9949ec3cb583de4a3a...
