I got interested thanks to all the postings in this thread...

I got a IBM T43 with integrated ATI graphics... (Not using ATI's closed
drivers!)
I am surprised at the fps I got:

fpeeters at fpeeters-laptop:~$ glxgears -printfps
libGL warning: 3D driver claims to not support visual 0x4b
3531 frames in 5.2 seconds = 684.670 FPS
5118 frames in 5.0 seconds = 1023.482 FPS
5064 frames in 5.0 seconds = 1012.749 FPS
5043 frames in 5.0 seconds = 1008.519 FPS
5043 frames in 5.0 seconds = 1008.436 FPS

(NOTE: first is low because I dragged the gears window of off the cli
window...)

Just wish the OSS ATI drivers supported proper XvMC and hardware MPEG
decoding, but that is a different story)

My mythtv FE/BE with nVidia's 8776 drivers on a MX-440 (MX-4000 AGP 8x
reported, which is definately incorrect! {It's a PCI card, you see?} And
yeah, I know it is old, but if it ain't broke don't fix it) gives:

mythtv at MythTV:~$ glxgears -printfps
2949 frames in 5.0 seconds = 589.679 FPS
2951 frames in 5.0 seconds = 590.013 FPS
2951 frames in 5.0 seconds = 590.179 FPS
2950 frames in 5.0 seconds = 589.912 FPS

(kinda disappointing, really, if you see all the extra work you have to do
to get the drivers working!...)
