Low FPS on "Debug Editor" Configuration

I’ve been playing around with the engine for a few days, mainly following along the intro to programming video tutorial. What I’ve noticed is that when I run the “Debug Editor” Solution Configuration my preview window FPS is anywhere between the high 20’s to low 60’s. Not the worst thing in the world, granted, but definitely appears odd. I’ve tried it in the other Editor configurations and those appear to work fine (Capping at 119.98 FPS)
