Ran a few tests on these drivers I got last night. They will not be distributed. All tested on a stock Athlon64 3400+ on an NVIDIA 6800 Ultra running at 461/1170 61.77 were the last non-WHQL released drivers on the NVIDIA homepage with 61.76 (untested) being the last WHQL. 66.02 was never made publically available and to my knowledge 66.60 never will be, tho I have had no issues with stability. No artifacts were seen on any of the tests and 461/1170 was the optimal range to overclock according to the NVIDIA drivers themselves with coolbits enabled. 3DMark 2001 61.77 - 23696 66.02 - 23011 66.60 - 23154 After a slight performance decrease with the 66.02 drivers after the 61.77 drivers, it was nice to see a slight increase in points. 3DMark 2001 is becoming more and more unsuitable as a benchmark. When 2005 is released this week I don't think we will see many big sites using 3DMark 2001 anymore. 3DMark 2003 61.77 - 12584 66.02 - 13046 66.60 - 13172 A moderate performance increase between 61.77 and 66.02 is improved on in 66.60.
