Blender (v3) smoke sim looks like dog crap in the viewport

Take a look here, in other peoples smoke sims, it gives a lot of detail of the smoke, with shadows or at least some shading. Was this dropped in V3? Or was it accidentally disabled by default?

As long as you don’t show any parameters on your screenshot, one can only guess.

I guess you have to check “Scene lights” and maybe “Scene World” in the viewport shader options.
