I hate to choose between Steam Overlay and ReShade. If I use D3D9 it works for me, but disables the Steam Overlay. I have no issue with keyboard nor my gamepad.
But yes, I wish that ReShade would work with this game.
EDIT:
I posted this eight months ago and I had this little voice in my head telling me to try Nioh again with ReShade for the last 3 days and now, yes, it iw working! DXGI 64 bit and with Steam Overlay, no depth access though. It worked with
version 4.2.1.
Now, if only Phanton Pain were to work now as well haha I did not find the urge to try it.
