Why can't devs deliver a "Next gen" graphics moment with PS5/XSX?

Because most games that are running on UE5 are upscaled from 720p and look like they are smeared with vaseline. UE5 requries significant time and resources to properly optimise and 80% of games running it are a mess on launch and continue having issues

There's this too. Not that bad but something like 856p and then upscaled to make a right mess of an image. I'd rather the aimed for 1080p 60fps which should be possible than upscale and ruin the image completely, making it look far worse than it would, would they just go 1080p native.
