Now my HTPC will need WinXp 32. Bah. No Vista 64 for my 3850. Sapphire.
Pff. Better now than when i have everything rigged up and running.
I suspect thats a bit of an over reaction Ive known bad driver versions for both operating systems, I remember one version of nvidia drivers for xp that were an absolute disaster for some of the games I played... In fact the one of the earliest drivers I had for my 8800gtx gave me some very nasty graphics artifacts in oblivion rendering the game unplayable, that was one of the main games I got the card for
it was fixed before long. I dont doubt this problem will be 8.6 seems stable enough under vista 64.
