Nvidia's PhysX driver will be released on August 5th, according to TG Daily. All PhysX compatible games will now be supported by capable GeForce 8, 9 and GTX cards.

This driver will support PhysX acceleration on all capable GeForce 8, 9 and GTX cards, while carrying Microsoft's WHQL certificate. More importantly, the new ForceWare driver is expanding PhysX support to all currently available PhysX titles on the market, including Ghost Recon 2: Advanced Warfighter, Warmonger and Cell Factor: Revolution.

We expect that downloads of free games such as Warmonger and Cell Factor will actually spike once again in August, since now those games will be playable on a variety of cards.
