No, there's a bunch of different OpenGL code between qmax and regular,
its weird that regular is slower though, the only reason I can think of
is because regular is using some mode that is software driven on your
card, but that seems *really* unlikely since you have a relatively
recent video card...

Is this is the latest CVS version?  There are some mouse bug fixes
checked in...

I don't think there's too much that can be done about this, except to
adjust the gamma through the game (look at the readme for directions)

Alsa sound is not quite 100%, I'd use alsa's oss emulation for now.

Hope that helps,
