Looks very interesting, so bought and downloaded. The installer adds assorted things to my system. When I try to run it, I get a "DX11 feature level 10.0 is required to run the engine" error message.
From DXDiag:
..
DirectX Version: DirectX 12
..
DDI Version: 10.1
Feature Levels: 10_1,10_0,9_3,9_2,9_1
..
Doesn't that mean I have it? What's it actually wanting?
