Red Dead Redemption 2 is one of the most technically impressive video games ever made. Its open world encompasses snow-capped mountains and dank swamps and wide-open plains and even a soot-covered city. The game’s designers clearly drew inspiration from 19th-century landscape painters in building a gorgeously rendered version of the American South and West at the end of that century.

But over the 30-plus hours I’ve spent playing Red Dead Redemption 2 on my HDR-enabled 4K television, something’s been nagging at me about the way it looks. It feels somewhat silly to complain about the visuals in this game, but I couldn’t shake the feeling that its HDR support didn’t make much of a difference. My suspicion of a lackluster HDR implementation was only heightened by the basic calibration tool in the game’s settings.
