In short there is only support for DirectX as of now, there has been talks about openGL/vulcan. But's it's still on the drawing table.

[JonSnow88]

so no opengl/vulkan games will work?

[zjoasan]

There is no dedicated support for OpenGL or Vulcan, but a lot of that "just works". And if I remember correctly, in dx12 there are some translation layers to make it work even better "seamlessly". But things like demand OpenGL or Vulcan unique stuff wont work.

Like checking if the display adapter has OpenGL, well it doesn't right now, Or if the game ask for supports some Vulcan DRM protocol from the display adapter, it doesn't support that either. We have a display adapter in VDD to connect the virtual display to, but it just have that function. The displays are then said to mirror the actual display of you real Display adapter (rtx2080 for example), which has support for most of these nice opengl/vulcan functions.

Guess what windows does when Display Adapter says, I got now screens? Do you think it tries put the games output to that adapter or a to an adapter that says I got 2 screens connected? I'm guessing you get a working game if you don't turn of the actual display?

I manage to get both OpenGL and Vulkan to work with the DirectX12.

We just need the OpenCL™, OpenGL®, and Vulkan® Compatibility Pack from microsoft itself.

@zjoasan can u update the Readme with this new information?

[zjoasan]

That information will be put there in a bit

Unfortunately, while this made the two games I was having issues with boot up, there's some weird graphical corruption, especially in the menus. So it is an imperfect workaround.

My best guess is it's converting coordinates incorrectly, since I'm seeing diagonal bands/lines of solid colors on part (not all) of the screen.
