just want to mention that scale by delta time is one of the modifiers you can add to an enhanced input action.
to test to confirm if you really need it or not, you can set the max framerate and then enter PIE and see that input is slowed down.
then enable the delta time modifier and now input remains consistent regardless of the FPS.
don’t ask me any follow up questions on subject, that’s all I know. 
just wanted to put this FYI in there cause it’s easy to miss
