I suppose the obvious pair could be midi and layout, followed by
bookparts. But I only have two cores and one is likely to be being
hammered by playing music from a video file.

Multiple threads will address your aside concerning LP's use of
multiple cores, but of course it has little to do with the OP.
Probably like you, I can't see what 3D animation has to do with
LilyPond. It's a bit like comparing an ultrawide paint roller with a
touching-up brush. One is simple and massively parallel, the other is
making complicated decisions, not what GPUs are good for.
