Why does display refresh charge change the sport performance and physics

Okay, so that is the flappy hen recreation easter egg on android 5.0 and 5.1 lollipop…Since i’m enjoying this on android 15 machine and a tool that has 120 hz refresh charge, i get this smoother and far simpler physics for no matter purpose…I bear in mind this recreation being a lot tougher than it’s on my android 15 machine, so i modified my refresh charge to simply test if that brought on this transformation in issue…

To my shock the sport now works because it did on older units…Clearly refresh charge contributed to this, however does anybody really know why this occurs?
