I'm using the Nvidia driver. I'll try the XFree86 version, maybe tonight.

I ran a couple of tests on other machines with similar results. One was 
an old 466 MHz Celeron with onboard ATI 3D Rage Pro 1X/2X. I think it 
has 8 MB of video RAM. In this case the penalty for double buffering was 
a factor of 8.5. The other was an 1.7 GHz Athlon XP with onboard 
GeForce2 (Nvidia driver), and the penalty was a factor of 9.
