it isn't rocket science senpai, higher refresh rate means your cpu and gpu sends in more frames, meaning much less delay between each of them and meaning your eyes being updated on the situation much less frequently
though once again, you get diminishing results as you go higher and higher, but the difference between 60 and 120/144 is night and day

try beat saber at 80 and then play the same song at 144 and see how much easier it is
