Is there any consequences for using higher polling rate? And is there any benefit of doing higher polling rate?
Unless you have a low debounce time on your switches and a fast scan rate it’s mostly just going to lower the maximum latency, you’d get better results trying out different QMK debounce algorithms. 1000hz shouldn’t have a performance hit unless you type at 9000 wpm though.

There actually is a massive difference in doing this, However this is mostly only going to be applicable when you are playing rhythm games. As the timing windows are so tight (16ms or lower for a perfect hit) an 8ms polling rate is very apparent and feels awful to play with. (disclaimer, I wrote this article)
