While I would consider myself a more than competent programmer, I've never done any game programming. So maybe there's just some widely known asset voodoo that I don't know about.

Hey PD,
No, there's no secret trick - I'm just using low resolution data sets. Usually no more than about 1000x600 pixels or so, hence the low file size. The one I like best (and will probably use for all future releases of the game) is the cleaned up version of the TOPO2 dataset found here:

The current version I'm using has been resized to 854x427 - I may include the option for higher res maps in the future but at the moment I don't think the increased file size and hugely increased load times are worth it.
