S3 has been releasing a lot of refrence drivers resently. Maybe these will fix your problems. Also there are a few beta drivers and hacked drivers floating around. Supposadly some of the hack drivers are a lot faster.
BTW kick yourself again. I just hope you didn't pay to much for it. Savage 4 sounded good on paper but never performed very well. Savage 2000 (ViperII) is closer to what i should have been, but is still a little off. Maybe their next card will be better.
