Here is a small difference between DX11 and DX12 (worst performance in my opinion).
Guide to Make the Game Run DX11/12
- Here is the DX11 version
- And here is DX12
To make it possible
To make it possible, you need to go to the game options (on Steam) properties>Launch options and put either -dx11 or if you want to test/stress your gpu: -dx12
It should look like that and that’s it.
