random mouse stutter (Very noticeable, probably ~100ms stutter) that occurs randomly 1-3 times/minute in desktop only
MSI b450-a pro
16gb micron e die @3800mhz
5700xt sapphire pulse (bios version 017.001.000.049.000000),
screen: acer ed347cr (3440x1440@100hz)
Mice: happens to both of my Model O and G502
Software: latest update to windows (OS build: 1836.2.418), GPU (19.9.3 and 19.10.1) and Chipset (220.127.116.113) drivers
New windows install, it also happened with my previous motherboard (asrock B450m/ac returned it for another issue)..Here's the weird thing.. the stutter is very noticeable, so if it happens in-game I would definitely notice it, but it NEVER happened inside games ---to me this screams GPU/driver issue, but i don't know---. If i'm watching youtube video, the video also stutter if i move the mouse in circles to induce the stutter.
Disabling 5700 xt driver in device manager fix the stutter.
changing the refresh rate from 100hz to 60hz fix the stutter.
Disabling freesync makes no difference
