I'm having a problem. My windows XP is original, and I had to re-install it.
After I did, i can't fide the "power management mode" on control panel
On windows 7 i can, on XP i cant. tried drivers since 177.92 and cant find this option on windows XP
My card is 9800gt
i cant find on NVCP. i guess this is marketing. You'll only have this option if you buy Windows 7.
i cant remember the driver version, but I had the power management to my 9800gt on winXP, but now there's no such thing. i even tried installing drivers since the version 177.xx and still nothing.
