Maybe. I'll recheck when I get there to be fair.
I use DX11 as it is currently faster, by around 6-10FPS vs DX12 at 4K. It's an odd one, but if reviewers didn't try running AMD on DX11, then they are showing a worst case scenario.
That was 4K, max settings, but with two settings turned down from high to medium (fog and reflections) and ambient on low instead of high - since there is no medium option.
I mean, there's no difference in quality there at all really, but the feeling that 20+ FPS gives you is huge.
I know you liked the effects dialled up, but i recommend you give it a try and see how it feels at higher FPS - assuming you have a 120HZ or better display. If you are running 60HZ fair enough, no point in that case tbf.
