Windows XP Driver
The current Windows XP NVIDIA stereoscopic driver is version 91.31 and this can be downloaded from the NVIDIA website. It is compatible with all GeForce graphics cards with the exception of the 8800 and 9000 series. It is not expected that NVIDIA will provide any future updates to their Windows XP stereoscopic driver because all development work is now focussed on Windows Vista.
Windows Vista and Windows 7 Driver
NVIDIA have now released a new driver that supports all their graphics cards, but it will work only on Windows Vista and Windows 7 (not Windows XP). This driver is compatible with 32-bit and 64-bit operating systems, and will work on all GeForce cards 6 series or higher configured in single or SLI mode. So if you want to play the latest games in glorious 3D then you will need these drivers! There is also a list of compatible games, which can be viewed here.
TriDef DDD Driver
In addition to the NVIDIA 3D driver which is available free of charge from the NVIDIA website, Zalman are now endorsing a third-party 3D driver produced by a company called TriDef. The TriDef driver is unique in that it offers compatibility with both NVIDIA and ATI graphics cards, and universal Windows XP / 32-bit Vista support. As well as enabling 3D functionality in most popular games, it converts 2D movies and photos to stereoscopic 3D! A 14-day trial version can be downloaded from the TriDef website, and if you like it, you can buy it for US$49.99. Furthermore, all customers purchasing a Zalman 3D monitor will receive a discount voucher code in the box which gives 20% off this price.
