Virtual Shadow Maps are Blocky even after using resolution controls

I am having the same issue as many others, jagged blocky shadows. I have already adjusted the controls for
r.Shadow.Virtual.ResolutionLodBiasDirectional -4
I’ve used higher values as well, but it has no more effect beyond that. I’m using a long lens and focusing down on some “painted foliage spheres” here from high up in the sky. For the project I’m working on, this is a required view, but it seems VSM are having issues resolving the shadow detail when at far distances with a telephoto lens/view.

Any suggestions?

I’m thinking that virtual shadow maps should take FOV into account when determining the resolution, but currently, it is not.

I’ve also tested by rendering a wider view at very high resolutions. The shadows remain blocky.
