No, because these D3D wrappers don't get loaded by D3D11 on Windows, they load D3D11 themselves. If anything, they are responsible for loading the "correct" implementation, but I wouldn't expect any of those projects to ever support anything other than the Microsoft D3D11 runtime.
Both ENB and Reshade work on Linux, so there's that.
I actually PRed this functionality into Reshade and Apitrace.
As for ENB, that's not open source so you'll need to bug that man yourself and I don't care to do that.
Nothing extracted yet.
Would it be possible to implement DLL chainloading into DXVK, to make it easier to load D3D wrappers like ENB, Reshade etc.? I'm not sure if this would be of much use on Linux, but on Windows it would allow these to be used without using DXVK system-wide, which is currently (as far as I am aware) the only way to do this. I am aware wrappers like these have no official support, but it would be nice to at least have the ability to load them.
