Bonjai comparing to an iPhone, the app opening and other window animations have less duration on Nothing OS, this duration is the default duration of Android I guess. Also the jump from 120 to 60Hz is huge, so our eyes will take time to adjust. My PC has a 180Hz monitor. Using my Phone(2) right after using my PC sometimes takes some time for my eyes to adjust. I haven’t had any devices which have refresh rate less than 120 or 100Hz so it’s sometimes difficult for me to adjust too.
I have checked if this is true on my Phone(2).
I never found any laggy applications but it took about a day or two to get used to 60Hz again. Although scrolling feels jittery in 60Hz after getting used to 120Hz. But that’s normal.
