NVidia has released a new driver package!
Drivers for x64 vista have been spotty to date but this update to nTune seemed to go a long way in providing me with decent system stats. It is also the only way we'll be able to OC the 8800.
Also, new 8800 drivers were released on May 2nd!
The install process is easier. I can now play texas hold 'em with out that nasty flicker. Stay away from the DreamScene content though, it apparenly causes major issues.
**Note** I would highly recommend running all of the control panels as administrator, they seem to crash when they are not.
