In total we have tested 25 graphics cards from AMD and Nvidia.
The latest official drivers were used for all graphics cards.
Such an approach works by accumulating sub-samples over frames and reprojecting them to the current frame.

It works on alpha tested geometry, and performs shader anti-aliasing i.e.
on surfaces using Parallax Occlusion mapping, or similar aliasing prone techniques.
We also ran similar tests using a range of processors from AMD and Intel to see how they compared.
