I was pointing that out because the other user seemed to think I was talking about a non-accelerated renderer. However, to access RT hardware and compute capabilities you need Vulkan nevertheless (or the non-portable ways that I guess Godot wants to avoid).

My original post was precisely about focusing on such a full RT renderer (via Vulkan). I am not an expert, so it may be a dumb idea, but it would be nice to have a FOSS production-quality renderer by the time full RT becomes a thing for more and more games.
