nVidia provides propietary drivers for the GeForces, just like ATi does 
(in fact they tend to be faster than ATi's in Linux). What I think is 
the key in particular discussion is the kernel and system specific 
optimizations. I know from first hand experience that a 2.6.x kernel 
improves DRAMATICALLY the game experience in UT200x. And I say this with 
this system:

CPU AMD Athlon XP 2200+
512 Mb RAM PC-2700
ATi Radeon 9500 128 Mb NP
Fedora Core 2 Test 3 (stock kernel is 2.6.5-1.327)
custom built 2.6.6 kernel (with bootsplash).
ATi drivers version 3.2.8 (3.7.6 are a LOT slower in UT200x, at least 
with my config).
ALSA drivers (instead of OSS) and OpenAL selfbuilt and symlinked to the 
ut2004 directory.
Stock UT2004 libSDL (for me did not provide much of an advantage to link 
to my system's one, contrary of what happened with OAL)

Only problem so far: I can't paly on-line, but *only* on-line games, SP 
works great and with good frames.
