Was meaning from the perspective of "I'm viewing a menu, this shouldn't max the GPU out". From another comment it does seem the video running in the background is being rendered in realtime, and maxing out the GPU.

I am not sure vsync would help in the menu, since the FPS is sitting below 60 in any case. Otherwise I'd agree with you that vsync should be turned on. It seems for FS that vsync is generally causing more issues than not at this point.
