The game starts okay, and the logo cinematics look okay (I think), but everything from the title screen onward seems to be locked to a pretty consistent 4fps. It's hard to casually diagnose without mangohud (https://github.com/flightlessmango/MangoHud/issues/835) but it appears that the CPU is almost entirely idle, and render settings don't affect the frame rate so I believe it's not at all GPU limited either.
Proton experimental 'default branch' is fine, it's 'bleeding-edge' that has regressed, FWIW bleeding-edge was fine a day earlier.

'Days Gone' (on Steam) - tried various in-game graphical settings from ultra low to ultra high.
