I actually tried No Man's Sky on linux few days ago and I had no real performance issues. Everything ran fine on ultra with a 21:9 1440p monitor and a 2080. I do agree that the performances are no the same than on Windows (15-20% less FPS on average). I don't know about the official proton for No Man's Sky, but I used the Glorious Eggroll's fork[0].
