Thanks.
I am running the editor at lowest as well. I am working on a slightly bigger than XL map, sure, but the file isn't at 7mb's yet.
I'm trying to find back the possible memory tweak that was posted with one of the latest patches but the old forums are offline again.
I have been searching for a possible memoryleak or anything, but no luck.
My MapEditor usage is at ~3,330mb RAM when first booted and around 3,520 mb's when the map file is loaded. Are those normal numbers?
I can understand that the software reaches 4Gb when saving the file, I suppose. But I'm not sure that would be the case for the actual game save.
I'm going to try and clean up any loose ends and unfinished additions, see if that smooths out the process.
Its possible that the increased size of map cause some of the problem. One thing could be said for the level editor that it certainly helps to reduce the size of the physical window of level editor.
On personal opinion I think lagre map is the absolut limit for maps to run smoothly inside game. 32 bit engines have a very delicat limit sadly
