@appelgriebsch Drawing conclusions from this (https://www.youtube.com/watch?v=j9TkzIKV9gY) video it's likely not the driver. There might be some potential for improvement on the driver side, sure, but you have to keep in mind that the Mali 400 GPU was announced in 2008. It did a great job in devices like the Galaxy S II (at a 800x480 px resolution), but it is just a pretty limited GPU in 2020.
