I'm getting alot of choppiness in online gaming. Even you tube videos are the same. My benchmark tests look all good but the GPU compute score is right at the top of the red. I've had the video card around 8 months already and this problem just started within the last few months. I have an ASUS Maximus X MB w an I9 CPU. Video card is Nvidia RTX2080 TI. My monitor has a 100 refresh rate and when the choppiness occurs the refresh counter jumps from 100 to 35 back and forth. Any advice I would appreciate. CPU and graphics card never get hot
