I am beta testing Fedora 41 and i have been monitoring how tuneD works.

Both balanced and performance work as expected, but powersave confuses me.
I had it as the active power mode (what is activated in Fedora Workstation 41's power GUI) and i noticed it draining a ton of battery, more than balanced.

I did more digging with cpupower_gui to see the active kernel cpufreq governor policy and i found out that powersave defaults to using the Ondemand governor.

Why are the technical reasons behind this governor choice? Wouldn't it make more sense to use the Powersave governor?

My CPU is a Ryzen 5 3500U, in the weird case this is a bug and the information is needed. My laptop uses the cpufreq driver.
