DCompositionCreate Device failed: Not implemented. (0x80004001)

This error occurred while running msedgewebview2. Is this interface outside the scope of what DXVK is supposed to implement? Should I seek help from the Wine developers instead?

dcomp is not implemented in wine, would need work both there and in dxvk to make sure we can present anything.

Hi,

I want to learn how to implement the DCOMP.dll and debug it.

Can dxvk built on windows?

So, is the correct approach is to implement a simple example using the DCOMP interface ,and run the example , switch between my own dcomp.dll and system dcomp.dll to compare the difference and verify the correctness of my implementation?

In regards to implementing dcomp.dll it is probably better to ask guidance from Wine devs. They have a IRC server if you use that https://gitlab.winehq.org/wine/wine/-/wikis/IRC
