Yeah, I've experimented with a lot of different looks. Many things seem to contribute to whether or not DLSS 5 looks good or not. Base Diffuse texture detail does matter a lot, but also if Spec, Gloss and Normal maps are too strong then DLSS 5 will likely overexaggerate them. Scene/background color and lighting contribute a whole lot as well (and can be quite problematic). But generally it seems like it works a lot better with looks that already have a more detailed realistic base. Stylized skin, depending, doesn't always give it enough to work with.
