Thank you all for your replies.
The gears problem is solved, but the slowness still remains, see
below.
setting FX_GLIDE_SWAPINTERVAL=0 make gears jump to 611 fps
q3a demo001 is OK, both with libMesaVoodoGL (3398 fps) from Q3A 1.11 and libGL from
XFree86-4.0.1h (31.8 fps)
But ut, heretic2, hg2, sof-demo all seem to render in SW (or at
creeping speeds in HW). Especially starting the games is really
slow. For sof-demo and hg2 no sound as user, but as root running X
(not as root in X terminal). Can the problems be due to the sound card
or the mouse?
Last in this mail also find the glxinfo output. (This program was
copied from RH, I did not find it in the Mesa-demos-3.4-4mdk package,
hint MDK, Mesa is not installed, to avoid dual GL libs)
