There has been quite a discussion going on over at the official Biobsidian forums regarding module size and related technical questions. So far, it's up to three ten-page threads. Today, several questions were answered by Adam Brennecke:
NWN2 tiles are roughly the same size as NWN1 tiles in terms of meters. Indoor tiles in NWN2 are a bit larger in terms of memory footprint, but outdoor areas are much larger. However, having a ton of placeables in areas, which we do, will greatly increase area git size, as well as the memory footprint of the area when it's loaded.
The NWN2 server will load all areas in the module into memory when the module is loaded. An area that is 'Active' means that it has at least one PC in it. Inactive areas will change AI priorities to a lower level, and being inactive will not free any memory. Active vs Inactive is how we control AI priorities and not memory usage. So a PW server with 90% area inactivity will run better than the same server with only 10% inactivity.
And finally, client machines only load one area at a time.
Brennecke, are we correct in assuming that small exterior tilesets will have a much smaller size than large exterior tilesets?
Yes.
I'd like to know if we can easily edit the world map.
Although this is slightly off topic - yes you can edit the world map.
What exactly about NWN2 exteriors, other than placeables, makes an area so big in file size.
