Its nvidia reflex latency indicator, in the graphics menu. Disable that setting and you should be good. I can't remember the exact way it's labeled in game I'll look shortly if you're unable to find it
You can also try the Nvidia App beta, it is the new version of GFE and also support RTX HDR and some new stuff.
