Just got a new phone (OnePlus Nord 3), turned refresh rate HUD in developer settings and I see some parts of the system and some apps display 120 Hz but I have problem noticing any difference, same with my wife’s Redmi Note 12, i have to look very carefully and maaaybe I notice some different, not sure
Yes, indeed. But I find it very, very noticeable when just moving the mouse pointer too. Looks horrible on a 60 Hz screen.
The most important thing I think is movement speed. Extremely slow movements would look the same at 10 fps as 1000 fps (think a movement of 10 pixels per second, for example), while large movements look choppy at lower framerates. That’s also (part of) why it’s more important to have a high framerate in Quake/Unreal Tournament-style games than it is in e.g. first person puzzle games, latency being the other big one.
