I am capping frames using in game settings or MSI + RIVIA.
Stutter happens when frames drop or frames drop when there is stutter. This two things are always together.
I've tested it in: CS:GO, R6:Siege, Fortnite, Rocket League, AC:Oddysey, Trackmania 2, GTA V.
Every game that I run have problems, sometimes maybe even at the OS.
It happens really randomly, even at main menus etc.
Even when I don't have any FPS limits, stutter still happen.
