Yes I see that, too, but rendering on the fly and then caching the results is a compromise between disk space and cpu power.
ACK. I'll try to get the necessary tool support.
Maybe packing the prerendered tiles into metatiles will solve it for the moment BUT I don't know how it'll be with zoomlevel 18 or maybe 19, 20 or even higher in some high density cities.
*Hillshading* is not really useful with zooms above 16 or 17 I would say, at least not with the DEM data that is freely available outside the US (SRTM3 basically). Contour lines might be useful in some areas.
When you say "high density cities", you probably are referring to road maps, and these can be rather aggressively expired if necessary, no?
