Battlefield 4 Mantle vs DX11 Review/Tests/Benchmarks

I didn't like most of the Mantle test on the web, because i think they are not realistic. They only test a high end PC vs mid-range APU/R9 290x (which is the perfect hardware scenario for mantle).

I, like for sure many more of you, have a mid/low-range PC and was currious about what Mantle could do for me.

As you can see by my results, Mantle makes things worse instead of helping, and the image looks a bit blurry.

Also, don't forget that both Mantle and the drivers are beta and are only "optimized" for the R9 290/X, R9 280/x and 2/3 more.
