Steam deck OLED cannot be turned on global FSR function in Quick access menu

I want to enable the FSR function by reducing resolution and enabling it in the performance menu. However, the MangoHud display only shows that FSR function is off. What should I do? Note: This function can be used normally in the Steam OS.

Did you also lower the resolution of the game to be less than native?

Just checked on my end and I'm completely unable to reproduce this. Make sure the resolution is actually lower.

I already set game to lower resolution ex: 1152x720 but FSR is not work and displayed image does not change. I found solution.It must turn all frame limit to Off (Vsync,Global frame limit),it's work but I don't want this.I want to enable FSR with frame limit to save energy.

is the game running in windowed mode (borderless might also work) while you have gamescope FSR enabled? i know some game require the game to be in windowed mode for it to apply correctly

I have tried turning frame limit on and off. If frame limit is on, the FSR display shows Off. However, the game image is still the same.
