Wireless Mouse Lag

Radio Frequency Interference

There does exist a problem with radio interference when using 2.4 GHz devices (Logitech Unifying Receiver / Bluetooth) along with a USB 3.x peripheral connected to the computer. This interference is known to cause significant lag in the mouse response (Intel, 2012). I would begin by investigating if this issue applies to you before moving on to other sources.

Simply identify if any USB 3.x peripherals are connected. If so, disconnect them and consider if the cursor movement changes. The USB 3.x issue causes erratic behavior in the cursor which should then be gone (Logitech, 2014). Remedies can then be taken such as changing up the USB port usage, and moving the mouse receiver closer to the mouse.
