Limits of making maps?

[Zylithan]

my computer has 2 gb ram dual core.... the 10kx10k map did not cause any slow down at all after RLE compression. Before that it did (like, GIMP was prohibitively slow.... took minutes to save or make changes...) ... I don't know much about what that means, but it seems to me like graphical complexity could be important as well as just pixels. but... i'm just making stuff up

So it sounds like the map size is dependent on computer memory then and not an artificial limit set by the game. Thats good to know . I only run 1.5 gig of ram so no 10k by 10k for me!
