These are all shots taken under the best of circumstances at 4k/6k on whatever Batcave Computer you're running on. Most gamers can't afford the luxury of 4k PC gaming, especially with GPUs getting more expensive. I think the point people are making is that Arkham Knight managed to do more with the technology they had at the time, than a lot of games these days, and it looks better overall. Anyone running on a high end PC can take cherry picked shots to show how graphically pretty a game is. But whether or not the game still looks that good in motion is another thing.
You posted Star Wars Outlaws. Most of the time the game doesn't look nearly that good, especially on consoles.
you need 4K if you have a 4K TV...
jump from ps3 to ps4 was big. jump from ps4 to ps5 is not as big.
jump from 720p to 1080p was not that big. yet jump from 1080p to 4K is bigger
maybe jump to 4K was the actual mistake. ps6 should and will probably fix this (with high quality upscaling)
there's also the problem of remasters and ps4 pro versions of games. most people compare ps5 only games to ps4 games that are enhanced to run on PS5. practically the best versions of PS4 games. take last of us part 2 for example. it looks incredibly BLURRY on PS4 to a point it actually ruins the image quality... ONLY, of course, if you've seen the best version of it. I'm serious. go play that game at 4k/30 or 1440p/60 on PS5, then go play with actual ps4 at 1080p/30 FPS
it is why it is actually rather unfair to compare ps5 enhanced ps4 games to ps5 only games. native ps5 games should be compared to native ps4 games. for example compare how star wars outlaws holds up compared to how rdr 2 held up on base PS4. let me tell you, it just looks horrible on PS4 if you've seen rdr 2 on a ps4 pro or xbox one x. even if you didn't, if you compare them side by side, both look amazingly blurry to a point you will the notice in what ways outlaws actually looks better
with that in mind, arkham knight on ps4 doesn't really look THAT great at 1080p. it doesn't use TAA, so it is not blurry to begin with. so this gives it a massive advantage over modern games that rely on TAA. but without TAA, game shimmers all the time. why is this being overlooked?
