Plan to use PhysX?

[Yuhaney]

Hopefully you don't use PhysX, since ATI's card work lot weaker when there's PhysX...
For example: Mirror's Edge.
Works perfectly on NVIDIA's card with everything maxed out but when you put even more powerful ATI's graphics card than NVIDIA's is, it stops working so good and frame rate drops a lot, since ATI doesn't support PhysX.
