How to Fix Mouse Lag in Windows 10

Mouse lag is another problem for Windows 10 users and normally force them to revert back to Windows 8.1. There cause is different from one to another Laptop or PC. The culprit could be your hardware or your OS configuration. Here is the common fix for the lag mouse problem in Windows 10.

1. Disable Cortana
Open Task Manager (don't ask why), if you notice the mouse lag gone you need to disable Cortana in order to solve your problem. If you love Cortana and still want to resolve pointer lag problem, open Task manager every time you want to use your PC.

2. Disable Intel Graphic or Nvidia High Definition Audio.
If your laptop/PC have 2 graphic chip, Disabling the Intel graphic would resolve the issue. In laptop terms, a laptop which have 2 graphics chip called Switchable Graphic.This feature use to control power usage with the ability to switch from high performance (Nvidia or ATI) to standard performance (Intel Graphic). You can disable Intel graphic by open Device Manager, Under display adapter, right click on Intel Graphic and select Disable then reboot. Remember this only applies for devices with switchable graphic.

3. Disable Nvidia High Definition Audio

If you have Nvidia Graphic, you can see Nvidia High Definition Audio listed on device manager, just disable it and reboot. It was reported to resolved mouse lag issue. You can enable the device anytime by open device manager- right click and select enable. It was reported that after disable with reboot, you can enable it back and it will not cause mouse lag again. If enabling it cause mouse lag again, you need to manually remove or rename FMAPP - see STEP 6.

4. Avoid Transceiver Interference 
If you have your transceiver located at the back. Move it to front USB slot because we want to avoid any interference. Even though placing at the back on Windows 8 or Windows 7 works great, it would not promise that it will works on Windows 10.

5. Update Graphic Driver with Latest Version
Default driver provided by Microsoft (along with Windows 10 installation) could be the reason for the lag. Go to the manufacturer website and download the latest driver version available. Updating using Windows update is not recommended. For Intel graphic, installing previous version reported resolve the issue.

6. Remove/Rename FMAPP.exe
For computer which uses Realtek or Conexant Audio, there is one file that run everytime you turn on your PC and it cause the mouse lag. The file name is FMAPP.exe,
You can see FMAPP run as background process on Task Manager

for conexant it located in
c:\program file or Program File(86)\forteconfig\
for realtek
c:\Program Files\Realtek\Audio\HDA\
The safe way is to rename both file so Windows will failed to run fmapp because we altered the file name.
The other thing is to remove forteconfig in add remove program in control panel. ForteConfig commonly found on Lenovo notebook which installed along with Conexant Audio Driver software installation.

7. Change the Palm Check Threshold
Go to Settings - Devices - Mouse and Touchpad -Additional Mouse Options - TouchPad Tab Settings
- Advanced Tab - Palm Check Threshold- now move bar all the way to the left

  1. Can confirm that "3. Disable Nvidia High Definition Audio" works for me!
    Thank you!

  2. For me, it seems it was the HP wireless keyboard kit (keyboard and mouse). The mouse was jerky but keyboard OK. I went back to a wired keyboard and mouse and everything is smooth again.

    1. Try the latest Win 10 updates, it seems to fix several issue with the Touch and input device, it could resolve your problem. In my case, my touchpad does not work at all and now after installing new updates it worked including touch gesture.
