Mouse lag with iGPU

Description

I have a two monitor setup, using an RX 480 for my main monitor and the iGPU for my second (the reson is a whole other issue with AMD drivers). After I installed the intel graphics drivers my mouse started laging. First I installed the Beta 15.40.26.4474 drivers and the mouse lagged continuesly to the extent where I could barely do anything with it (had to use my keyboard to reboot). After that I completely removed AMD and Intel drivers and reinstalled, this time I installed the stable 15.40.25.4463 version of the drivers and the mouse lag only happend very sporedicaly (usualy when I try to move it just a little) and is hardly noticable.

EDIT: it can get pretty bad on the stable drivers aswell

Always (100%):

Often (51-99%): X (beta drivers)

Sporadic (20-50%):

Very Sporadic (<20%): X (stable drivers)

Hi obi1,

Mouse lag issue is under investigation on Windows 10. We are trying to find the cause of it.

As a workaround verify if you are already using the latest BIOS version 1904 of the board the latest drivers for Chipset and Management Engine Interface.

According to Windows 10 support, they are recommending to disable Fast Startup.
