“The Radeon HD 4870/1G beats the Geforce GTX 260-216, and the 9800 GTX+ is slightly faster than the HD 4850. The outlier of the HD 4870 X2 is possibly caused because there isn't an optimized Crossfire profile yet - Nvidia's Geforce GTX 295 on the other hand is clearly up in front and we didn't recognize micro stuttering at frame rates above 35 fps. To push the Geforce to such frame rates you have to activate SSAA or one of the xS modes with TSSAA.
We activated the Physx acceleration for all our benchmarks. Our version of Mirror's Edge is a review code and thus the following results might probably not match those of the final version. ”
