I notice a difference in frame times fairly easily due to the stuttering, but can barely tell the difference between even 30-60hz on a flatscreen game (I do notice a difference when my desktop is <60hz though).
I’m a bit more sensitive in VR, but still can’t readily notice a difference above ~80hz. Sometimes I’ll clock it up to 120hz, but only for games that kick on motion smoothing since I can easily notice the difference between frame doubled 60hz vs 45hz.
I feel like I’m a freak or something for not being able to instantly perceive high refresh rates.
I remember when I first saw a high-def Retina Macbook, I didn't appreciate it. I happily programmed on my low resolution Macbook Air, snug as a bug in a rug.
I eventually upgraded to a Retina Macbook. One day I opened up my old low-res Macbook to recover some old files and I was horrified at how bad it looked. You could see the damn pixels! Text on that screen was so blocky. I couldn't believe I happily used that laptop for so long.
Is a Retina screen useful? Sure. Did my happiness increase? I don't think so. Does my screen eat up much more battery lighting up many more pixels? Probably.
Sometimes it's nice to be happy with the minimum and not ruin by chasing upgrades.
I just got Better Display[0] which works great for driving non-retina-density monitors with HiDPI resolutions that do anti-aliasing better.
