Playing around with operating systems in their beta stages can be problematic when it comes to driver support, as Windows 8-rocking gamers can no doubt attest; the graphics card beta drivers released for the various Previews haven't exactly been bug-free. Those error-rife days may be in the past for GeForce owners now that Nvidia has released new WHQL-certified drivers for the Windows 8 Release Preview.
Don't try using the drivers with any other operating system, however. Nvidia very clearly states that the 302.82 drivers shouldn't be used with other OSes, including Windows 7 and Vista or even past iterations of Windows 8. Feature-wise, the new drivers are a bit sparse. A bunch of the aforementioned bugs found in the various Windows 8 beta drivers have been squashed, and 3D Vision support was enabled in the Nvidia Control Panel.
