Ammonis and Steam Big Picture
When Your Library Goes Beyond Steam
Steam Big Picture is excellent when Steam is the center of your setup. Ammonis is for the PC library that also includes Xbox, Epic, Ubisoft, GOG, and more.
The short version
Steam Big Picture is the natural choice for a Steam-centered library. Ammonis is designed for PCs where Steam is only one part of the collection.
Controller-first throughout
Navigate games, launch actions, settings, and system controls from your gamepad.
Per-game performance
Give every game its own RTSS frame rate and Lossless Scaling settings.
Keep the parts of Steam you need
Open a game’s details in Ammonis, launch it normally, or jump into Steam when you need Steam-specific controls. You keep Steam and add a broader controller-first layer around it.
When Ammonis adds the most value
Ammonis is most useful when your installed games span several stores, or when you want display, RTSS, and Lossless Scaling profiles to follow each game from one interface.
