Plan to use PhysX?

[Shados]

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.

It's because when you run PhysX while you have an ATI GPU, you're actually running it on your CPU.

I'm one of the ones with an ATI GPU. I haven't really found a use for PhysX unless you either want to alienate more than half of your fans or want to have "pretty" useless particles flying around.
