This setting controls the maximum kernel frequency that the governor will use. However, it overrides the default, which for RPi3 is 1200MHz. In effect, it is throttling the RPi3 to have the same maximum cpu frequency as a RPi1. See https://github.com/retropie/retropie-setup/wiki/Overclocking for details on the settings. It is best to leave the config.txt as bare as possible, only overriding system defaults if there is a reason to.
Thanks for the pointer. When I built the rpi3 image, I used the existing rpi2 image we had, including the config.txt that was used.
From that wiki page, it seems that we're really under what both the pi2/p3 can support, including default values. Maybe we should at least bump this to "default" values (so not overclocking). So arm_freq set to 900 for pi2 and 1200 for pi3
Opinions ?
