[RESOLVED] Global FPS drop GROUP AI 5 SAM battery vs. 300 enemy static object

Once upon a time I was created a working MP server mission...

then I restarted the project with 1.5.7, result:

uncrontrollable airplanes everywhere because of constant lag

("CTRL"+"BREAK" FPS counter lying in this state)

Then I surprised, If I turned off blue SAM sites things came back to normal.

(not activated, group ai off, or in green alarm state)

When I turned them back ingame, FPS dropped to unplayable level rendered from ANY viewpoint/slot.

After some days of investination I surprised, after I deleted all red Static Objects

working blue SAM sites not causing lag.

samtest-5bSAMs_300rStatic.miz is intended for the first test to reproduce bug

(it has a F10 radio menu item for healing FPS ingame)

the two more mission is for proofing:

- 300 red SO not cause lag in itself

- 5 blue SAM sites not cause lag in itself (Hawk+Stinger MANPADS / Patriot)

the combination is deadly

samtest-0bSAMs_300rStatic.miz

samtest-5bSAMs_0rStatic.miz

samtest-5bSAMs_300rStatic.miz

I think you've just got a nail on a coffin here :-)

1.5.7.10175.378 solved the stutter completely for my original mission.

Thanks for the fix!
