I wonder of this might be due to your Linux nvidia driver (nouveau?) pinning the card on baseclock by default while the Windows one will allow it to scale up? Something I heard somewhere that seems applicable here.
In that case it might not be anything the game devs or Steam can do anything about but something you'd have to fiddle with on your system.
Happens with whisky and macos in my experience. It is like as soon as a game is installed and you do something like chuck a grenade, no explosion the first time ever you do that.
