If you do not know about it do yourself a service and make sure that it is turned off. Have had micro stutters every 10 seconds in most games for a about 6 months. Could just about put up with it for rdr2. It was more annoying in csgo. It made dark souls 3 unplayable. Initial Google results blamed my graphics card bios (rx 5700) and even xbox controller bios. Eventually I came across the windows game mode fix and it was night and day, no more stuttering. Beat the first dark souls 3 boss on my second attempt and ranked up in csgo in the same evening. What the fuck Microsoft. A game mode that decreases performance and is on by default?!
