Are we sure that this isn't just failing to find DXC or something? There are no obvious vkd3d errors in the log, certainly no shader-related ones.

Maybe it is RADV related then. I am not sure. Those Demos are primarily targeted to run on nvidia gpus. I don't have any nvidia gpus to countercheck VKD3D on them.

After installing mesa-git, the UE5.1 Demo by MAWI works now, probably due to this fix.:
https://gitlab.freedesktop.org/mesa/mesa/-/commit/91505132423bcf8949034ef277b8bee4e1936855

I marked the UE5.1 issue as solved with an updated winelog here.:

For more background infos about the probable cause for the fix read this thread.:

The UE5.2 Demo though starts now with mesa-git, but crashes after a couple of seconds.

Can be closed. No more crashes at start up finally.
