To put it simply, it's not working. I tried changing from DX11 to DX10 and still no luck. (No DX9 in Warframe)
If I had to guess, it's because Reshade is auto-disabling its depth buffer every time it's detecting a connection.
(Maybe, I have no idea)
BUT. . . In the previous ReShade version (4.2.1), It's working fine when I set it to Solo mode (no connection). And I tried using previous DLL and it's still working normally.

EDIT:
Actually no, It's also happening in SkyrimSE (64bit DX11), exactly the same as my video.
