If you look thru the 'glxinfo' I included in my last post, you'll
see that XFree got support from SGI and VA Linux. I suspect SGI was
the main contributer, as I read somethin a while back that they had a
falling out of sorts with nVidia, and decided to support Linux. It
appears none of the new 3d/accel support is from nVidia, and direct
rendering is still not supported. I gather they've (SGI) done all
they can without violating NDA's and licensing agreements with
Micro$oft, nVidia, and the rest of the Wintel gang. Still, I hope the
longer this goes on, just maybe the XFree people can guess the
missing info and hardware specs ;>
I guesstimate that current 3d/accel with 'nv' is about 30% the
performance the 'nvidia' driver, and not quite enough for a lot of
games, specially those that require DRI (eg, Flightgear). You can
get a little more oomph out of the 'nv' driver by usin 'nvclock'
(nvclock-0.6-2mdk) to overclock nVidia cards (10% is safe). I haven't
tried this utility with the closed source driver. Default for my GeF2
is 167 memory, 200 core. It runs fine at 185/225.
