@turanszkij As mentioned in Discord, this version seems to create invalid SPIR-V for some shaders.
Also, since I don't have a Mac, the dylib is missing, but homebrew might have the current version. Alternatively, the github repo should compile on MacOS

All Mac Developers automatically get Metal Shader Converter through XCode most likely, which includes a dxc dylib and executable. on Mac would it have to be gated by Wicked's versioning or by Metal Shader Converters?

I think we should use the same DXC version for everything. DXC changes details between versions and it sometimes has bugs (like eg. this version creates incorrect SPIR-V code). Ignoring the different APIs for now, it would make debugging between platforms more difficult since you have to take the different behaviour of the DXC versions into account.
