It seems as WoW ptr (9.0.x) works if you use wine-staging-5.15 (or possibly 5.14) patched with your D3D12 patches and compile it having mingw-w64 (as per winehq recommendation i guess).

vkd3d also works fine, or atleast aswell as it does on live.

Is there plans on implementing raytracing for RTX cards or its like? I think i saw you had a raytracing branch here tho.

The WoW logs sais this:

8/22 17:05:10.049  Choosing gpu by name: "NVIDIA GeForce RTX 2070"
8/22 17:05:10.049  D3d12 Device Create

8/22 17:05:10.556  D3d12 Device Create Successful
8/22 17:05:10.556  <IsGPUDriverOutOfDate> No

I kinda thought DXGI_FORMAT_B8G8R8A8_UNORM was supported? But maybe not "UAV" :)

PS. Interested in testing experimental branches if you want me to.

tl;dr don't expect this to be supported any time soon.

The DXGI_FORMAT_B8G8R8A8_UNORM UAV restriction is a D3D12 limitation, according to MSDN this format cannot be supported for UAVs, even optionally.

Hmm.. Seems to be "enabled" with nVidia drivers for Win10 with my GTX970 card tho.. (452.06 driver)

Maybe just some weird reporting from WoW? Or.. nVidia up to their usual antics of unsupported stuff :)

VKD3D explicitly disables UAV support for this particular format even if the Vulkan driver supports it (which Nvidia's does).

It's quite possible that the MSDN docs are just wrong or out of date, wouldn't be the first time, but it's optional anyway so right now there's no good reason to change it.

DXR works for WoW, if you build the dxr11-cleanup branch you can test it out!
