The right frame rate for every game
Set an RTSS-powered frame rate profile for each game instead of changing a global limit.
Per-game performance
Set It Once for Each Game
Give each game its own frame rate, display, and Lossless Scaling behavior, then launch it from the same controller-first library where you configured it.
One game, one profile
A global setting rarely suits every game. Ammonis keeps frame rate, display, and scaling choices with the title they belong to.
Lossless Scaling within reach
Adjust the full Lossless Scaling feature set from Ammonis without switching tools from the couch.
Set it once, then just play
Start Lossless Scaling with a game and close it again when the game ends—automatically.
What happens when you launch
When you launch a game, Ammonis can apply its display and RTSS choices and start the matching Lossless Scaling profile. Lossless Scaling can close again when the game ends.
What you need
RTSS is required only for RTSS-powered frame rate profiles. Lossless Scaling profile features require a separately purchased copy of Lossless Scaling on Steam. Ammonis remains usable as a launcher without either integration.
Questions, answered.
Do I need to own Lossless Scaling on Steam?
Yes. Ammonis integrates with Lossless Scaling but does not include it. You need to own the app on Steam to use its profile features.
Does Ammonis work without RTSS?
Yes. Ammonis still works as a game launcher without RTSS. Only RTSS-powered frame rate profiles require it.
