Hi,
I have programmed a small patch, which tries first to load AI-aircraft
from Ai_crafts instead of Aircrafts. It works fine and can help us to
save some memory.
Which name for the alternative Aircraft directory would be good? (For
simplification of the string operations it should have the same length
as aircraft has).
The patch is only a proof of concept (no comments, just one check for
...[2]=='r')...

Hi,
I was thinking about he memory usage of the aircrafts. As multiplayer
mode becomes more and more popular, more aircrafts are loaded into
memory. If any AI-aircraft is not loaded directly from the Aircraft
folder, but first from an AI-Aircraft folder and only if the aircraft
isn't found there, the aircraft is loaded from the Aircraft folder, the
memory usage can be minimized. We only have to copy the aircrafts with
huge memory usage to this folder and rescale the textures (and maybe
replace the .ac files by lower polygon versions).
