After using 144 hz monitors for gaming on my pc for a couple years now i get physicaly ill and nauseated at anything lower. I see people debating online about people not being able to see the difference between 60 and 144 hz... I play a lot of twitch based games and fast paced fps like overwatch as well. I went into my monitor and switched it to 120 hz..thats a 24 hz difference and even that has me sick to my stomach within a half hour play session. i also use to have issues with feeling that way on 60 always in the past. but since switching to 144 hardly ever. It looks like a slideshow when i see stuff in 60 hz now. Given that i seriously doubt i would not feel/see a difference on a higher refresh rate as well.
