Possible line of interest from the log: fixme:process:GetNumaHighestNodeNumber (0x32fb14): semi-stub
Distro: Linux Mint 19.1 Tessa (64 bit)
GPU: Vega 56
Driver/LLVM version: 19.0.1 - padoka PPA/8.0.0
Kernel version: 5.0.13-050013-lowlatency
Proton version: 4.2-7
Game is now playable, everything works out of the box except keyboard+mouse controls. When launching and starting a new game, mouse does not respond to directions unless you press down a mouse button. To fix this you can hit escape on the keyboard and then just resume the game, and everything works perfectly.
Including logs of replicating this problem:

Game works out of the box now without issues. Performance is a solid 60fps at 2560x1600 resolution with my setup, with just minor stuttering at the beginning of the game.
Including a log of a complete playthrough of the game for reference (I have completed the game on Windows too and did not spot any difference).

Note: An oddity is that the "fullscreen" option in the game behaves the same as "fullscreen windowed", this it also does on native windows too as far as I remember. So I don't think that this is a Proton issue. Closing, because I'm not seeing any remaining issues.
Nothing extracted yet.
