How to Fix Intermittent Mouse Lag
If the mouse has intermittent lag, moves poorly or fails briefly, it will affect the operation experience and even work and game efficiency. This article will provide a series of effective solutions to help you completely repair the mouse lag problem.
Step 1: Check the Hardware Problem
1. Replace the USB interface
If you are using a wired mouse, the USB port may have poor contact or insufficient power supply to cause the mouse lag. Try to insert the mouse into other USB ports, especially the rear USB port (directly connected to the motherboard, more stable power supply).
2. Replace or charge the battery (wireless mouse)
Wireless mice with low batteries may cause sluggish mouse movement or occasional lagging.
Replace with new batteries (AA or AAA batteries).
Charging the mouse should ensure that the charging is complete and try replacing the data cable for charging.
3. Try another mouse
If the problem persists after replacing the USB port, it is recommended to test with another mouse to confirm if the mouse itself is damaged. If the new mouse is normal, the old mouse may have a hardware failure and need to be replaced.
Step 2: Adjusting System Settings
1. Turn off the "Enhance pointer precision"
