XFX Radeon HD 5970 Black Edition Limited Review

Testing:

What would testing be if we did not show both sides of the fence? In this test, PhysX was set to low, while leaving the remaining settings intact. You have seen time and again where the ATI cards suffer when PhysX is enabled. Mirror's Edge and Cryostasis are two prime examples. Darkest of Days is no different. What happens in this test shows that although the game can be played by cards from the red team, the video effects and quality are diminished.

Settings

• 2xAA
• 8xAF
• Global Settings = High
• Physx Low
• Ambient Occlusion On

Higher = Better

Darkest of Days has dismal support for more than one GPU and as such, all the performance for all configurations was only as good as a single GPU HD 5870.
