The AMD control panel always shows 5-6 fps below the average in every game. For example Dirt Rally have it cap at 97fps it shows 92 Fe at 100 shows 94 RDR
The FPS limiter changes depending on your screen refresh rate, so at 40hz, it will give you the options 10/20/40 FPS instead of 15/30/60 so you always have even frame pacing! : r/SteamDeck
