It's really not much of a struggle if the game is good. Just takes a while to adjust to it. If you're playing on a TV and sitting the proper distance away from it, you'll get used to it pretty quickly. Humans are good at adapting.Answered it yourself.
It hard going from 144fps games back to struggling 30fps games. Nothing wrong with the game itself its just hard for me to go back and not something I look forward too. Tried to play some PS4 pro games yesterday and dam it hard.
