                Heretic videogame, 1994/1996, screens, higher resolution raster runs, 2021,

                4k raster (3840x2160),   _e3m2_   _e3m2_   _e5m8_   _e5m8_   _e3m8_   e3m5 (outside of walls)

                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,
