That's _very_ slow!
daul Athlon MP 1900+ (but SMP haven't much effect on this)
1 GB DDR266, CL2 (2x 512 MB)
MSI K7D Master-L (AMD 768MPX)
ATI Radeon 8500QL (r200)
I get this:
progs/demos> ./gears
Mesa: software DXTn compression/decompression available
10308 frames in 5.000 seconds = 2061.600 FPS
12314 frames in 5.000 seconds = 2462.800 FPS
12317 frames in 5.000 seconds = 2463.400 FPS
12316 frames in 5.000 seconds = 2463.200 FPS
quake3 (1.32b) gives at 640x480 windowed mode:
~136 fps with S3TC and sound
~160 fps with S3TC but _without_ sound
Check your installation.
Cheers,
