I have 3 things to say about this
1) These are beta drivers, so anomalies will occur, but THEY DO EXIST, so let's not get our panties in an uproar just yet
2) 3dfx gets kudos. Gigapixel acquisition looks like it may pay off earlier than Mosaic or Fear.
3) Benchmarks ARE NOT EVERYTHING. If it doesn't improve smoothness and playability, then the benchmark means nothing.
I'm reserving judgement until the WHQL-certified version of these drivers comes out.
If it does, then it means that the HSR drivers are not "dropping frames", as this would prevent it from being WHQL.
If a WHQL-certified version of these drivers DON'T come out, then that is VERY VERY suspicious, as 3dfx has prided themselves (and rightfully so) on producing stable, WHQL-certified drivers on an almost monthly basis since the release of the 5500.
Personally, I hope it works out. <g>
