NVIDIA has released a beta version 158.42 Vista driver for GeForce 8800-series graphics cards. The driver is available for both Windows Vista x86 and Windows Vista x64. Nvidia claims this driver adds support for SLI multi-GPU technology in DirectX 10 applications, improves both single-card and SLI performance, and brings compatibility fixes in "numerous applications." According to relase notes (PDF), the driver certainly fixes its fair share of bugs. Issues have been ironed out in Windows applications, Nvidia's control panel, and also 3DMark03 through 06, Company of Heroes, Dark Messiah of Might & Magic, Doom 3, Far Cry, FEAR, Gothic 3, Lost Planet, Neverwinter Nights 2, Rainbow Six: Vegas, and Unreal Tournament 2004. Users of GeForce 7 or GeForce 8600/8500/8400/8300 cards need not apply, though: Nvidia says this beta driver is strictly for GeForce 8800-series cards.
