Honestly when I have done with something, I don't want to return. That's how it is with Windows. I don’t want to use Windows in a VM just to be able to use any kind of software.
Yes, there is “GPU Passthrough” and “Looking Glass” to give you a bit of the "integration into the desktop environment" feeling. However, this is only fake and costs extra money (second graphics card, etc.) and efforts. As mentioned by @msdobrescu, “you leave Windows for a reason”. Exactly for this reason, I don't want to use Windows again. No matter by which methods. (I am not talking about Mac / IOS, because I absolutely despise Apple products).
And if after years - this post has been alive for 3 years already - and countless posts later, the developers still don't think that software on Linux could possibly make money, then I'm really sorry.
In that case, the only option for me, as a consumer, is to go without the Affinity software. I know, one swallow doesn't make a summer, but as a customer they will lose me for upcoming Affinity products or upgrades. At some point this should also be financially noticeable for them.
By the way, I find the idea of @Framelynx with a Steam+Proton version or the CodeWeavers port interesting. Only as a temporary solution, until a native version is available, but a bird in the hand is worth two in the bush ...
It feels a bit like the discussion about Star Citizen and Chris Roberts. The thoughts and a comment from one of the developers, about the current state, would be great. After three years of discussion!
