I first noticed it playing Warzone 2 but I quickly dismissed it thinking it has to do something with the game's terrible optimization but then later the same night I realized it was happening while I was playing Civ6. Now I realize it is happening in browser, windows, everywhere basically. As I move my mouse around the screen it just lags or stutters, it is hard to explain.
I don't really know where to go from here. I just play games, my knowledge on computers is pretty basic otherwise. Would a clean wipe of Windows be of any use in this kind of situation or is it something to do with hardware?
I reseated the RAM but it didn't change anything. The computer is around 2-3 years old, built it myself and never had a problem with it.
For what it counts the specs I can name are R7 3700X, 2070 SUPER, 16GB of Corsair RAM and an ASUS Strix Mobo B450F if I am not mistaken.
