Just in case you haven't seen this yet. :)  I haven't downloaded and tried them yet myself. I'll have to download after work tonight! I tried the 265.35 driver (Beta Version) and had problems with BFBC2 so I reverted to 260.99.

New in Release 266.58

Wow I didn't even notice that. Amazing isn't it...? Makes you wonder.

I find it interesting though that there is a Win 7/Vista 64bit, but not an XP. All the while, there is a WinXp 32bit but not a Win7/Vista 32bit available as of now.

It appears SLI now works in 3dMark11 with these new 266.58 drivers. I installed them, and the SystemInfo update for 3dMark11. I went from a score of P4300 to P7597.

Played BFBC2 for about 3 hours tonight. Not glitches at all. So they fixed the BFBC2 bug that they had in the Beta drivers. :)
