Good.

single core (no gpu usage)

Ok, that fits when i compare cpu speeds charts.

If you want to see the mesh ... best go for "pi" and not "2pi" ranges:

     .....
     normal   = "smooth",
     vector   = true,
] ;

lmt_scene_render ;

draw lmt_scene_mesh "gyroid"
     withpen pencircle scaled 0.05pt withcolor .8 ;
;

A nice stress test for pdf viewers (i tested sumatra/mupdf and okular).
