Pausing performance test and going back to graphics settings

[scootergrisen]

During performance test press Esc.
It says pause in the dialog.
But the test is running full throttle behind the dialog.
So i guess we cant call that paused.

When the test ends you get a button to go back to graphics settings. But you dont get that button in the pause dialog. so maybe add it there too.

The button is called "Back to video settings" but the tab is called "Graphics" so maybe it should instead be "Back to graphics settings".
