Warning: The drivers referred to in this article are still in beta test stage. Use at your own risk
It has only been 6 days since nVIDIA released ForceWare 177.83 with PhysX support. They've released 177.89 beta drivers which again feature a significant update; OpenGL 3.0 support. The release notes state "This driver is aimed at developers to start coding to the new OpenGL 3.0 and GLSL 1.30 features." I tried playing several games (Devil May Cry 4, Flatout: Ultimate Carnage and Assassins Creed DX10) without any issues although there was no noticeable difference in gaming performance over v177.83.
You can download v177.89 from nVIDIA Developer Zone and official driver download section will not feature this as it is still in beta. Note that the PsyX engine is not bundled with these drivers so you will need to download that separately if you did not install v177.83.
