30 seconds of initial load time is nothing for a game where you can spend hours floating around a galaxy. It's not a "load game -> play 5 minutes -> do something else" type of game.
As for not being able to imagine playing any FPS at 40hz -- I grew up playing FPS on computers which really couldn't handle playing FPS, pushing "entry level" $25 nvidia cards past their limits because I wanted the pretty graphics, 40 frames per second sounds amazing when you got accustomed to 15 ;)
About going from 15 to 40 I can totally relate. Been gaming on my laptop for past few years and have finally decided to buy a new rig. ~25->120FPS in Fortnite. I wasn't really enjoying it at 25FPS, but I'm living quite far away from friends so I used it to hangout. I wouldn't play otherwise, it's frustrating when everybody else is twice as good just because of FPS.
