I’ve been having this issue that started months ago out of nowhere. It took me a while to notice but once I did it’s been making hard to enjoy gaming or just using my pc in general. This issue happens more discretely outside of gaming but is still there. My mouse is completely smooth everything including scrolling feels really smooth. I’ve tried two GPUs three different high refresh rate displays multiple display port cables and I’ve reinstalled windows via windows settings. The issue still remains. My system: i5 8400 Gigabyte z370 d3 Rev 16 gb g skill DDR4 3200mhz running in dual channel. 650watt Corsair 80plus gold psu and a 2070 super.
