Although they have been out in beta form for about a month, Nvidia has now moved their 163.75 drivers into WHQL. The new drivers improve compatibility for Half-Life 2: Episode 2, and add Nvidia SLI profiles for Half-Life 2: Episode 2, Portal, Clive Barker's Jericho, Sega Rally Revo, NHL 08, and European Street Racing.

These drivers also fix a bug in the GeForce 6 series where the monitor loses sync when enabling SLI mode. As usual, they are available for download in Windows XP 32bit, Windows Server 2003 x64 Edition / Windows XP Professional x64 Edition, Windows Vista 32bit, and Windows Vista 64bit flavors.
