Barely worth running this program at 4k versus 1920x1080 -- four times the computation for finer edges between walls/ceilings/floors, some extra fineness for distant textures -- 15 watts versus 60, with this graphics card maybe.
               
more screens; some outside of walls, observation through outer walls, sometimes with uncleared-pixels retained image areas or smear-painting,
