You don't understand. I don't have access to these option. I'm on eea rom btw
They are there ... If ur talking about display tunables .
As for other stuff there's a way to enable more options:
Download setedit and change in global table the parameter called GPU tunner from false to true.
After that go to security app and clear data + uninstall updates ( I'm not sure if uninstalling updates is necessary so please try without uninstalling updates and let me know if it works ? )
After that open game boost , go to settings enable horizontal mode, return to add games menu and wait there for 30 seconds at least.
Close the app after that , remove it from recents as well .
And you're good to go , when you open the app again you'll see that everything has changed and more options are available including graphic tunables.
