Despite DICE being all gung-ho about AMD, Mirror's Edge: Catalyst won't even feature DX12 despite being delayed!
Looks to be doing fine on AMD hardware to me!
HD7870=GTX690
R9 280X=GTX780
R9 290X=GTX970
HD7950>GTX680,GTX670 and GTX760
Even their ancient CPUs are not doing that badly!
A "meh" showing if you ask me ...
If AMD wanted to be competitive in this game an R9 290X should have at the very least been equal to the GTX 980 since we know Fiji has poor scaling to compete with GM200 ...
So,shifting goalposts then.
But if you mean a meh showing for Nvidia then agreed. So why are so many Nvidia cards underperforming the game??
The whole range of Kepler based cards are being destroyed in a Nvidia sponsored game by slower AMD cards.
The GTX970 can barely match a R9 290X,and the R9 390 tends to match an R9 290X or beat it:

The R9 390 ands R9 390X show improvements in performance over the earlier versions,so even in your worst case scenario,an R9 390 should be around the same speed as a GTX970 and a R9 390X not much behind the GTX980,as its 10% faster than an R9 390 and R9 290X.
If that is the best that Gameworks or no DX12 can do now that is really a waste of money!!
Last time I checked on Steam,the GTX970 is the most popular enthusiast card - so why is it underperforming in a Nvidia sponsored game??
So,much for all your doom and gloom.
