[AP]so, the infamous the-longer-you-fly-the-slower-you-get problem - resolved

[fireanddream]

I started my save at stable ~170 fps, after 155 hrs of gameplay, today I was like, this is getting worse, this simply cannot be 170 or my eyes are lying. Checked with fraps, I'm having 40 fps in station and ~30 flying in space. Still running with the right graphic card and no graphic option changed.

I do have a couple of complexes, about 120 owned stations and an 87 station complex in savage spurs, but that shouldn't be the problem.

EDIT:
Did a bit of search and it seemed to be generic mission memory allocation problem which has been bugging people for a while. Resetting mission director restored my frame rate but I also want to keep my active plot missions. <See MD reset thread here. Alan Phipps>

EDIT2:
It was not the generic missions that slowed me down, as I used the 3.01 Generic Missions.xml file to disable all generic missions and confirmed none of them was offered in game (though the icons still appeared). The problem seems to be subcue L3M02, in which my HQ, hub, shady business and player corp plots have a variety of cancelled cues under their names. They added up to ~600 cancelled cues.

Old save game without doing anything: ~43 fps flying
Disabled generic missions: ~55 fps
Reset MD: ~70 fps
Fresh start (same sector): ~110 fps
Old save game + kill all NPC ships: ~46 fps

I'm really puzzled right now.

After a bit of seta-ing my md reset save game dropped to ~60 fps, too. So I guess the generic missions were to blamed.

If the icons for the generic missions appeared, then you haven't disabled them correctly. Find the spot that sets the weightings (relative chances of each spawning) and add "*0" to the end so the result must equal zero. No need to touch the code further down. Bad things happen when I do lol.

There's only two generic missions that account for well over ninety percent of the framerate degradation that comes with sector swapping. Both are to do with convoys. That's what I found in my games anyways.
