Games run faster on SteamOS than Windows 11, Ars testing finds

As a semi-related aside: I often read of people complaining that Fallout New Vegas crashes constantly for them, but under GNU/Linux using Proton I get none of that, I can play it for hours on end without any notable instability.

Those are likely people that don't check the pcgamingwiki, one of the first things it mentions is installing dxvk and the 4gb patch.
