nVidia's drivers evolve as fast as their GPUs :-)
So far I've only glanced at some results from Intergraph's
"3D ExerciZer" OpenGL demo -- swapping the May-2000 driver
that came with my GeForce2 card, with nVidia (beta) 5.32
detonator drivers raised "3D ExerciZer" frame rates by:
Texture Stress: 40%-55%
Light Stress: 8%
Processor Stress: -2%
Polygon Stress: 23%-29%
Then there is the evidence that the GeForce cards are Quadras
with two resistors changed... the Quadras have all the high-end
CAD OpenGL features turned on -- AA lines, advanced clipping,
and I guess a different implementation of hardware picking?
