 Note high memory usage during world gen (roughly 1.5GB at start of world gen) seems to be related to having GRAPHICS set to YES. See 0000217:0000747

 I have to often kill the process once I have quit the game, keeps running in memory. Vista SP1 also. I use the default Init file so my memory footprint is much smaller after I quit DF. Usually around 150MB

 First, graphics was set to yes when I did this.

Second, tried with latest version:

- Memory was 400-550m.
- After creation the memory dropped back down to 200m.
- Exiting didn't result in the process being left over. This may have been my OS complaining about the memory (or the game).

So this probably can be closed as fixed in 0.31.02

 Tried again, this time with exactly the same seed.

1.5gb to 490mb during gen
1.5gb to 220mb after returning to menu
and no left over process after quitting.

What part(s) are you reproducing arcaner?
Computer specs might help too.

 @Greyhawk On my system Dwarf Fortress does not quit cleanly. A process will still be shown to be running in the task manager after the window has closed. Quitting after world gen the assigned ram was around 1.5 gig, without world gen the assigned memory was about a meg.

Running Windows Vista Business SP2.

 Your right, it definitely has a problem still in 0.31.03. I created a map and embarked only to have incredible slow downs for my entire OS. I exited and the process was left behind. Memory use never exceeded 1gb though and the process only had 200mb left but was still taking cpu time.

 Does anyone have any updates on this one?

 Closing due to the lack of corroboration for recent versions.
