DIRT RALLY antialiasing benchmark

hi, i just tested dirt rally 1.1 on

AMD 270x oced
3570k 4.4ghz
8gb ddr3 1600
win10 x64 pro
latest AMD driver in April 2016, 16.4.1
1080p, everything ultra but advanced blending (off, it chops like 50fps)

i am not going to explain about anti aliasing, there is good info on the internet

but a quick resume:

* cmaa, just like fxaa, mlaa, taa, postproceesing AA, it is like (looks like) 3x msaa (better than 2x, worse than 4x) without the performance hit

* msaa, the good old classic AA, but very expensive on performance

 * eqaa, some weird  new AMD antialiasing, NVIDIA has another AA, it should be better than msaa with more performance, for example 2f4x is 4x msaa + more aa with less performance hit than 4x msaa alone and looking better, so if you can you should use these as they are better than the old msaa and perform way better

so there you go, the results, normally i would choose 4x msaa if i can have 60fps perfect, but  not this time, so i will go to CMAA, it looks great with no performance hit, i cant really tell the difference between every mode of AA
