I had a similar problem when trying to sync non-steam games, then I stumbled upon syncthing. I’m hosting it on my Pi, so it would sync for me even when I’m offline, but being at a different place is an issue then.

May I ask what your host is running? I was also trying this, but running Linux with wayland is not doing great work for me. I wasn’t having issue under x11 tho.

It’s pretty much the same for me, basically only use it when I’m to lazy to sit infront of the pc or I’m simply just not at home.

I do have to admit the syncing over Steam works amazingly, I can stop playing on my pc sit on the couch and my latest save is already on there.

I have been playing a lot of BotW and DRG on it. Playing BotW on it is amazing, for DRG or mainly any shooter on it there is the problem of me not being used to aim with the gyro properly yet.
