Are the 6693 drivers the best right now or are there any others that work well. I'm experiencing some strange artifacts in some demos, HL2 in the beginning the surfaces that are suppose to be glass at the tops of the gates dont look right they are sparkling. In Farcry demo from PC World parts of the sand in the beginning dont look right. are demos just crap or is there a problem with the card/drivers. running DX9c, the 6693 drivers on Win2000.
