I then tried the 174.74 BETA driver... Couldn't even log into the character select screen. Took that one out.
Tried the 175.16 BETA Driver... that gave me around the same performance as the certified driver but resulted in a driver error aftre about 30 minuets of game play.
The best results (while it worked for me) was the 175.63 Beta Driver. Which was the newest one I could find through google and Guru3d.com. I had an average of 39-40 FPS in the Hub Cities. 52-65 FPS outside of the cities. The only draw back I could find was I received a driver error when I went into certain areas of the game. If I stayed out of these areas I had no issues at all and everything ran perfect.
Hell with the 175.63 driver the game said I was getting an average of 250 FPS (which I really am not sure if it is possible) in one of the single player instances. I was in this instance for over 1.5 hours and never dropped below 240 FPS.
I was wondering if anyone else was using 64 bit Vista and an 8XXX series card and what drivers they are using. Along with any trial and errors with the different drivers if they have so tried different drivers.
Any feed back would be greatly appreciated as I'm trying to find the most enjoyable visual game experience I can get.
