I am Formatting my pc for performance issues and i want every single of my game saves to be synced in the cloud but for crysis (bought it obviously in GOG) cannot find a way to back uo my saves in the cloud

I'd like to know the same thing. I've just gotten back into PC gaming after a long, long hiatus. I just beat Crysis today, and I'm wondering if GOG galaxy, which claims to have cloud saves like Steam, will actually back up my save files/settings/etc.
