Cyberpunk 2077 on PC is the reigning champ of video game graphics. The sheer quality of its visuals across the breadth of its world is simply unmatched. Combined with its incredibly art direction, nothing comes even remotely close to Night City.
Runner up is Red Dead Redemption 2. The scale and detail Rockstar pulled off on an Xbone is a miracle, and it only looks better everywhere else. Go anywhere and it all looks spectacular. No linear corridors, no fixed time of time, no bullshit; it's a feat for the ages.
Everything else might look good, but as we've seen in this thread, its the same five screenshots posted every time - and for some games, its almost always just cutscenes that look drastically different to gameplay. They have their moments, but, with Cyberpunk and Red Dead Redemption 2, in gameplay, they look astounding.
