- here is an example of this.The stuttering happens independently of whether i am in an app or just on the home screen. It appears for around 10 to 12 minutes and then everything comes to normal. My gpu is a gigabyte gtx 1080 and the cpu is a ryzen 5 2600, psu is a cylon 600w .Tried undervolting the card, did not seem to do anything. I suspect the reason of the problem is cpu/gpu throttling but i'm not really sure. Also, sometimes when I open task manager . it for a bare second shows my cpu being loaded up tp 90%. Thanks in advance for the answers
