Hmmmm. I play GT Sport online mainly and I’ve noticed on streamers videos that the resolution and frame rate is noticeably better, albeit marginally. Graphics are important on racing games in my opinion. On Red Dead the frame rate is woeful at times too.
I’ve got a decent Panasonic 4K TV and don’t think I’m getting the best out of it as I don’t really use it for anything else.
Probably worth it for you then mate.
