In the question and answer they did on reddit on 3000 series they mention that DLSS 2.1 added support for VR. This is actually the location where it got me most excited if it taken advantage of and we see higher resolution VR head set.
This is my personal taste so other people might vary but for me when it comes to what I would like to see in different categories
E-sports - High refresh rate, resolution less important
Single player experiences - 4k, HDR and other eye candy like ray tracing etc but most the time am fine with 60hz on the refresh rate
VR - Greater then 4k and High refresh rates and I would give up some eye candy for those 2 things because you basically looking at a screen though a magnified glass so not noticing pixels require a very high resolution and because of the nature of VR not having a min of 90hz become a issue. Higher then 90 would be better.
If DLSS allow that high resolution with a high refresh rate and still get some of the eye candy that would be awesome for vr
