Maximum memory for one map?

[Verdite]

I'm busy creating my levels for Rathmor (working title), and I could use some advice on maximum amounts of memory for one map. I dont mind adding or subtracting enemies if I get crashes in the runtime, but I make image maps for my maps now, so having to cut down placed map pieces would be a pain.

If anyones got a rough estimation on maximum map-piece vertices for map areas, i'd like to know ‎
