A week after the launch of the GeForce 9800 GX2, Nvidia has released drivers for both the new dual-GPU graphics card and its more affordable cousin, the GeForce 9600 GT. This new 174.53 release is the first GeForce 9800 GX2-compatible driver set to have received Windows Hardware Quality Labs (WHQL) certification from Microsoft, and it includes support for Quad SLI technology, new PureVideo HD features, and new Nvidia Control Panel functionality for Windows Vista.
The new control panel features include "Manage Custom Resolutions," "Adjust Television Color Settings," "Adjust Screen Size and Position," and "Move CRT Position." Users can also look forward to the following new PureVideo HD functionality:
Dynamic Contrast Enhancement Dynamic Blue, Green & Skin Tone Enhancements Dual-Stream Decode Acceleration Microsoft Vista Aero display mode compatibility for Blu-ray & HD DVD playback
Naturally, that last feature isn't available on Windows XP. Nvidia doesn't list Quad SLI support as a feature for the XP version of the new drivers, either. (Although we don't suspect there are too many folks willing to blow $1,200 on DirectX 10 graphics processors and then run Windows XP, which only supports DirectX 9.)
You can find the 174.53 drivers on Nvidia's website in Windows Vista 32-bit, Windows Vista x64, Windows XP 32-bit, and Windows XP Professional x64 flavors. Release notes in PDF format are also available for both Windows Vista and Windows XP.
