Nvidia is really pushing its support of hardware game physics via their PhysX driver support embeded in their regular GeForce driver updates. Today the graphics chip company released their latest official reference drivers for their GeForce line-up and they include improvements for two PC games.

The GeForce 190.62 drivers are "optimized" for both Batman: Arkham Asylum and Darkest of Days. Both games use PhysX drivers to help with their in-game physics effects. The drivers also have a number of bug fixes. You can download the release notes for the full story on the new drivers which naturally come in Windows XP, Vista and 7 flavors.
