New WHQL-certified version 275.33 drivers are now available for NVIDIA graphics cards. Among other things, the new drivers address a performance issue with The Witcher 2 running under the beta 275-series drivers and offer Windows 7 performance improvements for several PC games for GeForce 400 Series and 500 Series GPUs compared with the previous WHQL drivers. There are drivers for Windows Vista, Windows 7, Windows Vista 64-bit, Windows 7 64-bit, Windows XP, and Windows XP 64-bit. Thanks Charles.
