Significantly better on DX12 for me on my semi-ancient hardware. DX11 is stuttering like hell. Could be because of 4 GB ram, for which very high textures are not recommended. DX11 1080p 1x Fury @1040/500 i7 930 @4.0 16.7.1 Spoiler DX12 1080p 1x Fury @1040/500 i7 930 @4.0 16.7.1 Spoiler

I just tried running this bench again, DX12 with a Fury and it's still a stutter fest unless textures are dropped from very high to high. I was getting an overall average of 38.8 and minimums were around 8 seconds in the first area and then 2s in the next area and 0.something seconds in the last area, That was the second of two runs which was the better of the two. There's also a square shaped area in the bottom right side corner, that seems to be missing certain effects like shadows as it is a lot brighter when the area around it is darkened, It's a big square too, between 1/5 and 1/6 of the screen. The game itself with textures at high runs great.
As long as its not 30fps like the bench results I'm more than happy to play at hobo texture settings.
