My system:
i7 4790k
1080 Ti
16GB RAM
Win 10
Game-settings:
- 1620p
- maxed out, except:
shadows: high
objects and streaming: 7/10
no CA, no motion blur
I ran the benchmark several times (3x DX11, 3x DX12), with driver-versions 419.17 and 419.35.
There were no performance-differences between driver-versions except for an odd one-second-freeze in DX12 with 419.35 in a certain scene.
Overall, DX12 runs smoother, stuttering feels "less stuttery" and the lowest framerate was 61FPS (DX11: 53FPS).
In taxing scenes like the shootout, I got a FPS-boost of 5-10 frames in DX12.
But ingame, DX12 seems to be kind of broken for me because the game crashed several times and the ingame menu stutters a lot.
Have you tried disabling the Uplay overlay when using DX12? That's supposedly helping to solve crashes based on users' reports.
