I read on the SVN that Koshling had reduced the memory footprint for the mod (yay!). Does this apply mostly to gfx memory or normal RAM? (I have lots of one and not so much of the other.)
Also, would it be possible (when someone gets some gets some spare time, this is low priority) to reduce the poly count on some models, to help the graphics card? I (and probably many others *looks at DH*) would appreciate this very much.
Normal RAM. Graphics memory is outside of the code we have source for, in the main Civ4 engine which we have no way to modify. The only way to affect graphics memory usage is lower poly/res models (as you suggest) and lower graphics settings I'm afraid.
