Today we can bring you new Vista drivers for NVIDIA GeForce graphics cards. The drivers in it's original form are intended for the upcoming new GeForce 8600 graphics cards.
We included a modified .inf file which you can try and use as it'll make most graphis cards compatible.
This is a BETA driver, if you run into a setup error (unlikely) you can always install the old-school way; thus:
> Control Panel > System > Hardware > Device Manager > Display Adapters > your graphics card > Driver > and hit Update
Then point to to directory where you extracted the files. Again ; this seems to be a beta driver treat and respect it as such.
