Why can't I find my cursor or see the cursor's movement trail on screen? How do I fix it?

This is usually not a mouse malfunction. When DPI is set fairly high (e.g., around 2000 or above), the cursor moves in larger jumps each time; on a standard refresh-rate monitor, the movement trail looks discontinuous and hard to follow with your eyes, so it seems like you can't find the cursor. We recommend lowering the DPI a bit first; you can also try raising the polling rate.
