For what you are looking for, i would suggest to use only the FRTC to cap the framerate to the desired value.
Chill works the best when you got, would say 130 fps, then it drop to 30fps when doing nothing, idling.
But if you have fairly low fps output, i don't see why mixing Chill and FRTC, just cap your framerate at 60fps.
You should have a far better game experience.
As far as I see it, Radeon Chill does not work properly on my R9 FuryX, Fury, Nano, down to R9 280x or HD7970 cards.
In game keyboard only input FPS is limited to Chill min + 25 FPS for all games I tested.
Plenty of examples here: Could AMD please add Keyboard and Mouse input Weighting sliders for for Chill in Adrenalin Driver?
I just tested 18.7.1 Drivers Wolfenstein II : The New Colossus - YouTube
Please see the comments in the video for more information.
Perhaps it does work on RX 480/580/Vega56/Vega64?
I do not own those cards.
I do not run Chill. I use FRTC so I save at least some power but get good performance in game.
I am not the only one then...
Hialgo Chill used to let you set variables in the game to scale the keyboard only input FPS or the Mouse input FPS etc.
Please see the links above.
Is there an updated list of all the 'supported' games with Radeon Chill?
Last up to date information I have is from 17.7.2. release presentation.
I think Wolfenstein the New Colossus II title is supposed to be supported as it is a new Vulkan AAA title and I read a write up regarding Radeon Chill used on the game.
