They are incomplete but..

Driver 1.0-251 with NV-AGP
800x600 16 bpp 1346 frames, 20.1 seconds: 67.1 fps
1024x768 16 bpp 1346 frames, 20.1 seconds: 66.9 fps
1280x1024 16 bpp 1346 frames, 20.4 seconds: 65.9 fps
1600x1200 16 bpp 1346 frames, 22.4 seconds: 60.2 fps
800x600 24 bpp 1346 frames, 20.4 seconds: 66.1 fps
1024x768 24 bpp 1346 frames, 20.9 seconds: 64.4 fps
1280x1024 24 bpp 1346 frames, 24.2 seconds: 55.5 fps
1600x1200 24 bpp 1346 frames, 35.5 seconds: 37.9 fps

Driver 1.0-251 with AGPGART
800x600 24 bpp 1346 frames, 17.5 seconds: 77.0 fps
1024x768 24 bpp 1346 frames, 17.7 seconds: 75.9 fps
1280x1024 24 bpp 1346 frames, 23.1 seconds: 58.3 fps

I have the evolution of all the drivers from 0.9-5
This machine Is a Bi-Pentium III (Katmai) cache size : 512 KB
The distribution used is Mandrake 7.2 XFree86 Version 4.0.1
512 MG of ram and a Geforce 2 ultra kernel in evolution :) now it's a
2.4.5-pre4 next week 2.4.6-ac3 (maybe)
This test is not even a good bench (quake III arena timedemo demo001)
With perfly town the frame rate doesn't get less than 63 frames our
projects work fine with linux this 32 bpp suggested is only 24bpp in
nvidia linux, the visual sensation of the AA is better with 24 bpp.
