The Skyway from 350 m at rest with the detail normal: the far tiles at the ring's step (8 cells in the near ring, 32 in the far one), yesterday's numbers off the flight line.
The same moment with the detail high, the default on the big tier: every far tile at half the ring's step (4 and 16), about four times the triangles of normal; in a corridor's cone they go to a quarter (2 and 8).
The same moment with the detail max: every far tile at a quarter of the ring's step (2 and 8) while you are slow, sixteen times the samples of normal; at speed max is high, because a quarter-step tile costs seconds to bake on the vales.
