It works in ATI cards without problems at all , nVidia really pushed this tech far :

They fined the algorithm to do more specific work instead blurring everything like MLAA does now, FXAA is less aggressive with numbers and texts and result in better performance due to better tasking.

You can obtain a close result setting MLAA to x2 and Narrow-tent, but FXAA is still doing more clean work.

Recommended without doubt for single players (aka happy campers) sessions
