I still hope this migrates to Linux since lately Windows 11 has been working very badly. D5 is based on directX12 which is well supported by proton so it is not impossible for them to deliver any information that does not compromise their product to make the proton and Wine guys do their magic. They would be the first real-time RT tool for architects on Linux (I said for architects look that it is easier than doing everything by hand in blender), they do not need to fragment by just aiming at they should .deb they would already be covering most of those who work in Ubuntu, they should and open the possibility that the community itself will adapt and help them move forward.
