For this to work,you need to set your phone to dynamic mode
Then you head to the scenario profile of your favourite game,and enable hardcore tuning
Then slide every slider there,to the right,like so
That way,xmode or advanced mode or even durable mode won't override your settings with pre configured settings and instead your own hardcore tuning will kick in
The results are self explanatory,the phone goes all out even more than if it was xmode or advanced mode,with more stable clocks too
