I noticed today that the xbox client of NGS may have a bug where if you turn on the graphics option "Screen space reflection" on that after awhile your screen may flicker at random to black flashes and if you stand still and rotate camera your screen may go entirely black.
I have all options turned on to max settings on my series s on a 1080p TV except the following which are off
Screen edge darkening - off
Blur - off (personal preference never was a fan of blur)
Last time I replicated this bug was when I teleported to central city and the screen was black. Turning off screen space reflection instantly restored the screen.
