The game looks amazing, it's a bit difficult in the begging as it should be but when you get used to it it ROCKS!!! I've noticed some stuttering so I hope that will be fixed in an update or with a new driver from Nvidia (DX12 cuts the frames down by 20%)
I have the opposite experience when playing. I saw all the hoopla about DX12 not being as good as DX11 when playing, but...
In DX11 I have horrible GPU usage, goes from 50% usage down to 2%-7% usage constantly, back and forth, multiple times per second. CPU usage always 100% across all cores. When DX12 is enabled, GPU usage is usually around 85%-95%, CPU usage always at 100% across all cores.
Yup, highlighting to me that my 2500K at 4.5GHz is no longer up to the task. I need Zen or Kaby Lake with a quickness.
