AMD Radeon 6000 Series Image Quality Analysis
This page tests three DX10/DX11 games using regular MSAA against MLAA. Note that AvP 3 couldn’t have 8xAA enabled so I used 12xCFAA instead.
There’s one redeeming result for MLAA and that’s with AvP 3, where its performance is the same as 2xAA. In the other games it has a major performance hit and is equal to or slower than 8xMSAA.
