Finally, after months of promises Nvidia released a new set of drivers that enables PhysX on G80 (the first 8800 series) video cards. This new drivers supports all cards from 8800 series to the latest GTX280.

This release, Nvidia ForceWare Drivers 177.83 WHQL, comes with a new version of PhysX System Software. For starters, you can download some demos, an Unreal 3 patch that enables PhysX and a free game that supports it, Warmonger.

In the download page, there is a video encoder, which i think supports CUDA for using the GPU to encode video.

Oddly, the downloads are provided via Java, so it sucks but at least the speeds are great.

Note: If you experience longs waits or the installation fails, extract the contents of the installer to a folder and move the PhysX setup to another location. Then, run it after ForceWare successfully installs.

If you ever get any problems when updating drivers you can use Driver Sweeper after you have uninstalled you current drivers to clean your system for left over files. After that, reboot your computer and install the new ones. This will reduce the chance of having driver issues.
