540p is a pretty low internal res, which can also highlight issues with DLSS. The point being.....I don't think DLSS is amazing, yet, either. and seems to be game dependant. A couple of games, it is pretty darn great. But several, its ok. and a few, its pretty bad.So UE5 looks good, but it's not as good as DLSS. It looks great in static shots, but in heavy motion there are dis-occlusion artifacts and blurring. See this video I recorded.
It's on 1080p native monitor with scaling at 50% (so an actual render resolution of 960x540). It does look very nice considering for 540p. But notice as I spin the camera around, there is a halo around the character.
This is common with temporal based solutions, and probably can't be fixed completely. DLSS is also temporal based, but it's more complex and the artifacts are definitely less noticeable than Unreal 5.
