This issue can be related to your mouse settings, and you might get better results by setting your USB to a lower polling rate.
250hz is for most the best compromise, and that is the polling rate recommended for most mice, as it offers very slight jittering and still delivers good responsiveness at a higher malfunction speed.
Make note that most newer gaming-grade mice have very high malfunction speed, even at low polling rates, so you may not even have to worry about that.
Some newer mice also have polling rate changing options in their driver, so that makes it easy to modify and play around with.
