Nvidia's PhysX technology dramatically improves the mood in Batman: Arkham Asylum for the PC
Batman: Arkham Asylum is the first PC game to use Nvidia's PhysX technology to good effect.
We've criticized PhysX in games like Tom Clancy's Ghost Recon: Advanced Warfighter where added explosion debris was the only noticeable benefit, but the extra debris is only one PhysX effect among many in Batman: Arkham Asylum.
The Physx-enabled fog adds an effective layer of gloom to many environments throughout the game. You can use Batman's detective mode vision filter to see through the fog too, so it doesn't become annoyingly obstructive.
