If youâre extremely sensitive to mouse response, you may notice a difference. But keep in mind that most monitors only refresh at 60 Hz or, at best, 144 Hz. Youâre much more likely to notice performance issues related to the quality of the mouse sensor than due to the polling rate.
DPI just means precision. Higher DPI means greater precision/smoothness for your mouse movement. For example, in lay-man's terms, with a higher DPI mouse, you have a better chance of landing the pointer on a pixel you want vs. a mouse with lower DPI (correct me if I'm wrong) You can bump up the sensitivity for average mouses (mice?), but you will lose the precision.
