Yes, just change the value to performance and it will take effect immediately. You can just input Code: echo 'performance' > /sys/devices/soc.0/1c00000.qcom,kgsl-3d0/kgsl/kgsl-3d0/devfreq/governor with root access (devel-su) in the terminal and thats it. Though the setting doesnt persist between boots so after every boot you need to change it again. I found it just by doing a search of the word 'governor', found the path that has 'kgsl' on it (like on Jolla1) and tried it. Not a god either
