My old workstation (dual Athlon MP 2000, GeForce 4 Ti 4600), 6629 drivers:

20150 frames in 5.0 seconds = 4030.000 FPS
20126 frames in 5.0 seconds = 4025.200 FPS
20228 frames in 5.0 seconds = 4045.600 FPS

Can't wait to bench my new workstation -- Athlon 64 3500, PCI-Exp. GeForce 
6600GT. :-)

Was gonna try to see for myself this evening, but for whatever reason, I can't 
even get X to actually work with 7167 on my main HD playback box at the 
moment... Will try again tomorrow night with another box. If I get that 
problem myself, I'll rebuild Myth against the 7167 libs and try again.

It was definitely compiled against the older drivers, its just that I believe 
you could shift between versions prior to 7167 without a problem. Seems 
nVidia might have done something different this time to break that ability...

I just don't use it. Just benchmarked my Athlon XP 3200 some after wiping it 
and putting CentOS 4 on it. 50% cpu usage on 720p programming, 70% on 1080i 
w/kernel deint enabled. No XvMC. :-)
