Hi @JohnnyRacer,
I have thought about dynamic adaptive resolution many times, and I know that SpaceX presentation on their 2D prototype. In 3D it's a game-changer for many cases, but also an implementation nightmare on GPU. You need splitting/merging of coarse/fine cells, make sure it's only 1 resolution layer change between neighbor cells, handle streaming at coarse/fine interface with indirect addressing, reorder cells in memory, and for every finer level compute 2x the number of time steps. It's a multi-year effort I'm not yet willing to take.
I'll keep it in mind, but close this as "not planned" for now, as there is some more urgent construction sites to finish.
Kind regards,
Moritz
