Hi,

I installed the NVidia 61.77 reference drivers for my Creative Ti4200,
and got a 20% boost in performance; going from 9900 in 3DMark 2001 to
11000 or so. There was a near doubling of the frame rate in the nature
demo section of the benchmark.

Best regards,
Paul

I have never noticed any improvement with newer drivers on my 4200. Especially
with 3Dmark as a guide.
Which driver version did you upgrade from? I might give the 61.77's a try based
on what you posted. I don't believe I ever tested that version.
