I hope this is the right section for this. For a little over a year, I have been playing DCS on linux via wine, and a bunch of people have told me to make a thread about it on the forums.
If you're interested in also jumping off the windows train, there is a (mostly) up to date guide on getting it working at https://github.com/thezoq2/dcs_on_linux and a bunch of discussion about it at https://github.com/ValveSoftware/Proton/issues/1722
The game runs pretty flawlessly, though there are some issues: the biggest one being broken smoke rendering https://github.com/TheZoq2/dcs_on_linux/issues/4, and a few other minor things. Performance is pretty good in my experience though I can't compare to windows because I haven't tried it on this PC.
Of course, there are no guarantees that this will keep working in the future, but it's nice while it lasts. Usually patch day requires some investigation, but so far we've been able to keep it working.
Finally: ED, in my experience, there are several people who are interested in this and while I know you probably don't have the resources to do anything official, I, and I'm sure a lot of other people would be very happy if this keeps working. If we can do anything to help with that, let me know, I'd be very happy to help
