The detail has to be there in the scene and file. @123sg examples above for instance (rodeo and car) have very little fine detail or texture.
I’m an RT user and the detail you get from RT/ART has been unrivaled for years. At least in practical terms as you can probably get similar results with other software but with RT/ART it’s just there.
It’s worth noting that capture sharpening in RT/ART does give a bit of pixel level “grain” to blurred transitions. Wide continous transitions become a bit noisy so for blokeh fest photos it’s worth tuning down or off.
