Ok i think might figured out seem but said countless times but give shot seem EMI coming from monitor i using alienware AW2721D 240hz HDR but did same prior gsync monnitor. Out of countless things i bought including countless new PC parts, I got one of those $150 heavy shiwlded PSU cable from bestbuy for my PC. It seem to help but not all time.
So today bored i tucked my displayport cable under my PC and noticably better but seem to slowly creep back. Seemed like PC was blocking EMI. I got idea take high end power cable from PC and use it on monitor and its working so far. consistently stable no charge buildup.
So yea seem like more power PC consumes more floaty mouse gets. Even cell phone changers unplug them from wall even if in another room. also I had t go into my mom ipad turn off all facebook BS that counstiantly connecting online even that helped.
So yea try better power cable for monitor plug into monitor and see what up. You can return it if doesnt work. Ill give update tomorrow.

Also what i said also about 8k viper high recomend if you play at high refresh make even smoother awseom and think working better becasue thicker better shielding cable.
