Interesting that in CPU limited benchmarks (800 x 600 or less) the scores are lower. If 3dfx ever do fix all the errors I hope they have a control panel toggle so you can enable/disable HSR. I prefer to drop the gaming resolution to get the highest possible FPS when I play.
The results do look promising, and if 3dfx get HSR to work perfectly (ie no errors in any game) they will be very competitive.
