This is great! Thank you so much. The only thing I modified was the "PerformanceShowerBG" I set the Anchors to the top right corner because with my widescreen the box was out of the viewport.
I do have a mini suggestion, the lowest FPS value stays the same for the whole test period. It would be cool if it would reset every 5 or 10 seconds in case the initial loading of the scene or a certain asset isn't what I meant to be testing.
5 Stars!
