Just now, NVIDIA has made a new Quadro graphics driver available, namely version 321.10 belonging to the 319 family, which offers compatibility fixes and improved performance over previous updates and is also WHQL-certified.
The release consists of several download records compatible with Quadro notebook configurations running under Microsoft’s Windows 7 and 8 operating systems, and with Quadro, NVS, Tesla, and GRID desktop systems that have Windows Vista, 7, or 8 installed.
In addition to that, NVIDIA’s update also includes drivers targeted at its Quadro SDI capture card, which can be installed on Microsoft’s Vista and 7 platforms, both 32- and 64-bit architectures.
However, in order to work properly, these SDI-related files also need a WDM package that you can find in the drivers’ description page (the WDM release is suitable for the same OSes as the Quadro SDI drivers).
As for the XP OS, NVIDIA hasn’t made available the drivers (yet) for either desktop or Quadro SDI users, but when the producer outs them, you will find the files in the link below.
That being said, download NVIDIA Quadro Graphics Driver 321.10 for the proper system configuration, apply the update, and enjoy your newly updates graphics card.
