hi y'all
i got a ASUS v9950 or Geforce FX 5900 to be precise,
the problem is if i install a forceware driver 6x.xx, all games really run terrible

(normally 40-90 FPS, now 10-35)
At the installation of the new driver the installation sais: Cant pass the Windows Logo test, but i set this error to ignore, it still didnt help,
the latest driver i can run at is 56.72 which is about a year old... :nxs:, which is (what a coincidence) the last 5x.xx series driver
so can anyone explain to me why i have the driver problems?
