Low frame rate on balenaDash RPi4

Thanks @tmigone

I am following this thread(WittyPi power management board with a RPi3 docker container - #3 by zuma) for installation instructions, in the wittys install script ther is the following code

if grep -q ‘core_freq=250’ /boot/config.txt; then
echo ‘Seems the frequency of GPU processor core is set to 250MHz already, skip this step.’
echo ‘core_freq=250’ >> /boot/config.txt

I assume its to make their hardware back-compatible with all pi versions

Any ideas if its possible to overcome this or increase the FPS another way?
