At the top of the stack sits Xbox One X, rendering natively on ultra HD displays and looking magnificent. Taking the runner-up position here is PlayStation 4 Pro, which uses a reconstruction technique - likely checkerboarding - to take a native 1920x2160 framebuffer up to 4K.
Muddying the waters here a touch is the temporal anti-aliasing solution, which seems to interfere with the quality of the reconstructed output, giving a double-width pixel effect that emphasises the original 1920x2160 image, and it is noticeable on a 4K display. While it can't be completely ruled out, we found no evidence at all of dynamic resolution scaling (DRS) on any of the console versions of the game - the pixel counts are locked. Take a look at the screenshot comparisons on this page, and the X advantage is undeniable.
Despite its immediately apparent resolution advantage over PS4 Pro and its massive boost to pixel count over Xbox One S, the X also has a tangible performance advantage over every other version of the game. Red Dead Redemption 2 targets 30 frames per second, frame-pacing is consistent on all platforms, but there's a clear difference in performance in the game's busiest areas, with the enhanced consoles clearly running more smoothly. Once again, top of the pile is Xbox One X. Bar one cutscene that strangely runs slower on X than any other platform, Microsoft's enhanced machine delivers a nigh-on locked 30fps with only very minor dips in performance in the most detailed city areas.
