Once expected to hit alongside the PlayStation 3 and Xbox 360 versions on August 25, the PC release of Batman: Arkham Asylum has been pushed back to September 15 in North America and September 18 in Europe, publishers Warner Bros. and Eidos said today.

In addition, the pair revealed that the PC edition of Rocksteady's detective comic brawler will make use of the PhysX technology supported by NVIDIA's GeForce hardware.

Batman is now more physical than ever before. On the PC, at least.

"Supporting NVIDIA PhysX technology has allowed us to add that little bit extra to the PC version of the game," explained director Sefton Hill. "As Batman interacts with the world, the aging asylum creates a more immersive, believable world."

Though the retail release has been delayed, the downloadable demo is apparently still on track for tomorrow, with more on the PhysX effects following below:

With PhysX technology enabled, players can explore darkened corridors packed with volumetric fog which reacts to Batman's movement and cobwebs which tear with his passing. Combat becomes a maelstrom of motion as office papers are thrown into the air alongside soda cans and litter as Batman lands each punch upon The Joker's henchmen. Throughout the game, the decaying gothic architecture is realized to an incredible detail with wall tiles chipping and breaking, stone pillars crumbling upon impact, and particles from breaking glass and debris shattering and falling down around Batman's feet."
