If you have the patience, this thread is for Q90T users that mostly use it for gaming.

It's a lot of pages to go through though.
Personally, my son hasn't complained with his PS4 but, he is 7. It all seems fine to me but that thread link above has stuff about all different types of consoles, pcs etc and is worth having a cuppa whilst you read. It has some good settings on some pages too. If you are gonna spend that much on a gaming TV, it's worth researching.
The stutter issue for me, only happens on Sky Q broadcasts at certain frame rates. So if you are using it as a TV at any stage linked to Sky Q, I wouldn't bother. I'm in the process of choosing a replacement from another manufacturer.
Good luck.
