I have the latest 21.81 driver for my Geoforce 3 card and it works great, giving somewhat of an increase in speed.

When I first installed them however I had a bit of a problem. The aquarium screensaver went from 60 Fps with the old driver to 28 Fps. Eventually I discovered that by changing my settings from “Quincunx Antialiasing” to “Allow applications to control the antialiasing mode” it went back up to 60 Fps.

Then later I found that I could get eliminate the refresh rate being locked at 60 Fps (on both the old and new drivers) by running the DirectX Diagnostic Tool. To start it go to Start | Run | dxdiag | More Help | Override… and change the setting. After doing that the refresh rate jumped to my monitor refresh rate of 75 Fps @ 1280x1024 (vertical sync on). In windowed mode I get 182 Fps @ 1280x953x16 or 133 Fps @ 1280x953x32. (Athlon 1.4 processor)

Once you get it set right the new driver should give a significant increase in speed.
