FPS preformance increase when wing is hit/Off in the F-16C

[yorenb0203]

So while I was flying my F-16C on the Syria map I noticed a massive fps increase when the Slats and the wing tip got shot/hit off by gun/Missiles, my fps went from 10-20 to 40-120.

So after I noticed this increase I did some testing and tried to remove non necessary variables like what other players are doing on a MP server. So I setup a testing area with the F16C controlled by player and some SA-9 (this is the same unit that caused the original fps increase). And after many attempts I got 3 tracks where you can see a massive fps increase when one full wing gets blown off and the 4th track file is an almost exact replica of what happened originally.

I don't know, does the flight model stop running after a certain amount of damage?  (just a guess)
But, from my testing, I thought the scenery was the cause of the big fps drop (i.e. P-51 fps = F16 fps = F15 fps (with same scenery settings) - but all have different flight models).
