Batman: Arkham Asylum is an action-adventure stealth video game based on DC Comics’ Batman for PlayStation 3, Xbox 360 and Microsoft Windows. It was developed by Rocksteady Studios and published by Eidos Interactive in conjunction with Warner Bros.
For our testing we set everything as high as it would go, except for Physx and NVIDIA Multi Sample Anti-Aliasing.
Benchmark Results: The Radeon HD 5850 is ~19% slower than the Radeon HD 5870, but still dominates the NVIDIA GeForce GTX 285 in this benchmark. With the Radeon HD 5850 running in CrossFire mode it was able to beat out a pair of GeForce GTX 275 graphics cards and a GeForce GTX 295. It should be noted that even with PhyX turned OFF in Batman: Arkham Asylum a performance loss is seen on the NVIDIA SLI enabled cards. We disabled PhysX in the NVIDIA Control Panel before entering the game and the performance nearly doubled in this benchmark. We ran the SLI enabled NVIDIA cards with PhysX enabled and disabled in the control panel to show you the performance gap, but keep in mind that PhysX was always disabled during game testing Batman: Arkham Asylum in order for the benchmark numbers to be more apple to apple.
