Albion Prelude V3.1
Close to vanilla, however obviously necessary to go modified to run script to assist factory building, benchmarking, resetting Mission Director and more.  One of the goals was to remove as much load on the CPU as possible with exception of whatever player factories / complexes existed for each.

It appears to be not possible to have a framerate of over one thousand frames per second in X3 Albion Prelude.  I know it was in X: Beyond the Frontier as in that game I regularly saw over 10K FPS.
Where framerate is 1000+ below, FRAPS showed 1000 solid and not dipping under it. Which means it could be any figure above or equal to 1000 but not below.

Target accuracy was 5 percent for all tests.  The greatest error by far is coming from how CPU caches work, and how sensitive X3 is to raising and lowering of performance for seemingly little reason.  Although all NPC stations, ships, asteroids, debris and planets were removed from the universe, the X3 engine occasionally spawns new ships and stations anyways.  But the figures below vary sufficiently I think to make them useful.  If you cant find the save file on my website to match each case below let me know and Ill see if I can find it and upload.
