ConfirmedNo. It’s the manager not being able to control the DVFS. The DVFS is doing as it pleases. If you disable it in sys/devices/platform/17500000.mali by removing read and write permissions from “dvfs “, “dvfs max lock” and “dvfs min lock” you will be able to use the frequencies you set up. (You have to use a root file explorer. A decent one). Unfortunately it’s a temporary solution, as it resets every reboot.
I assume DVFS is also the thing dropping frequencies for no reason on the CPU. If it’s not a timer nor temperature related
Disabling DVFS by revoking all read and write access making GPU run at any freq we set in hKTweak (even 572Mhz all the way long). Plus we need to disable game booster, game optimizer and friends. Those thing make instant re enable DVFS by itself (not even until reboot).
