Thanks for the link, checked it and well even side by side on my mbp, the difference is not that super obvious. 30 to 60 fps is very obvious and night and day. 60 fps and 120 fps, I only notice the difference side by side if I pay attention...

But maybe it's because I'm 40+ with relatively bad eye vision and 20 years earlier I'd be noticing the difference much more.. But I'd say going from 1080p to 4k was a lot more obvious than that...

I've never understood the 120hz hype. Sure it looks a tiny bit better, but I'd trade that in a heartbeat for more battery.
