I've added the rename to use copy engine. We should decide about the booleans vs the bitfields for the reasons outlined above.

RT64 will _always_ prefer the dedicated graphics card. This just sounds to me like the GPU is not visible at all to the application when you boot it. Do you...

Add a breakpoint to this [line](https://github.com/DarioSamo/RT64-HLE/blob/c144df7aae279d3a4873e919daa8f5d36d737ce3/src/d3d12/rt64_d3d12.cpp#L2966) and tell me how many times it hits it and show me the contents of adapterDesc in the debugger.

Apparently your integrated graphics cards supports Raytracing while your dedicated GPU doesn't. I guess that's not good enough of a hint. :)

I've written down the issue and it should be fixed in a future update, thank you for the help. Now go play Quake 2 RTX with your iGPU.

Metal as a backend is something that could be easily implemented into the current RHI. It is a great API for this project and it'll be a natural fit. However,...
