Cloud saves seem to work for me for Witcher 3 - Game of the Year edition. But an issue I am having thought is I have both a gaming pc, and a gaming laptop. Now my laptop isn't nearly as powerful as my main gaming pc rig, but it is still pretty decent.

But so far when testing I noticed that when using GoG Galaxy and using the cloud sync, it not only syncs the save games, but it also syncs the graphic settings. I noticed this first when I had to put the settings like down to medium or so on my laptop then it changed when I launched it on my desktop?

I am wondering is there a way to change it so it only syncs the save game files and not the graphic/game settings? since it is kind of annoying to have to remember and to change back to my settings on my desktop whenever I would play it on my laptop?

I have the same issue. I installed BGEE on my PC and laptop, both are in the same network. On PC cloud saves are syncing fine but on laptop there is a message "Cloud Saves not synced". I tried to run the update but it didn't help. I have noticed that when I clicked the saves backup on my laptop the gog downloaded saves and characters that were created on my PC to !Downloads\!Cloud Sync Backup in the game folder but they are not available in the game itself.
