Your patch history shows Linux updates for 60FPS in October 28, but GoGs version is June 29.
I can't easily play because none of my controllers work for it.
Scouring forums shows that a Steam update in August fixed the problem.
It's not on GoG.

The 60FPS update and controller support. These are reasons that I bought the game.

When will I be able to play this?

Also curious to know, just bought it assuming that it would have the current version ;_;

Does anyone know the current state of the Linux version here on GoG? Mainly whether it has the 60fps support. I see there was a patch adding content on 23 June 2017 but reading the changelogs on steam it seems the 60fps may only be in the testing branch on steam for linux still (in 'main' for windows and osx), not sure what that means for the GoG version.

There's an 'FPS' setting and it defaults to 60 FPS for me.

Nice and smooth.

Thanks a lot for replying, good to know.
