According to GOG, their new Galaxy client is coming out of Beta soon with several changes. The most notable will be cloud saves.
“This new feature makes it possible to add cloud saving functionality not only to new games but also to titles that never offered cloud saving before. Thanks to this, excellent games like Planescape: Torment, Heroes of Might & Magic® III, or Vampire®: the Masquerade – Bloodlines gain the benefits of saves syncing and cloud backup for the first time ever.”
Other new features will be added such as an in-game overlay, screenshots with the F12 button, an FPS counter, a revamped chat window, a hibernation mode to reduce CPU usage, and more.
The new version is available right now for the beta testers and will available to everyone in April 2017.
