Honestly, at 30Hz you can feel the input lag. It always feels like the mouse is a little behind, and the key you pressed isn't quite there yet. It's only 33ms, but you can definitely see it.

60Hz is quite usable but if you are used to 120 or 144Hz you will notice it immediately.

Scrolling is gross too

Now you've got me curious. I've been playing with various Bluetooth and 2.4GHz-proprietary-wireless mice, along with a cheapie wired one, and never noticed much difference. But it's always been at the same refresh rate.

Brb, finding out what my screen maxes out at.

30hz is a non starter for me no matter what task I am doing.

It gives me some nasty headaches too.
