Slow graphics performance

I am having real issues getting sufficiently fast graphics
performance.  
 
Here is the CPU information:
Dual processor Pentium
Nvideo graphics controller V34 (GFX 5200)

Here are the outputs from glxgears and the opengl -info command:
 
glxgears
1958 frames in 5.3 seconds = 369.800 FPS
1920 frames in 5.3 seconds = 364.159 FPS
1920 frames in 5.3 seconds = 360.915 FPS
1920 frames in 5.3 seconds = 361.136 FPS
1920 frames in 5.3 seconds = 361.087 FPS

GLX gears ran very jerkily.  However I have never seen it running.  I do
know that people running similar systems have reported much higher
speeds according to the archives on the FC6 mail list.  I will see if
there is a better video driver, possibly on the nvidia website.

I appreciate any help you may be able to provide.

Regards,
Les H
