FPS hit, black screen, and then CTD

[Tango777]

I was flying in the PG map, it was a Create a Mission, and Single player. Daytime with no weather. Flying thru thru combat between blue planes and red planes (good vs. bad guys) with no problem, and then I was about 5,000 ft. above 4 enemy tanks out the corner of my left eye with nothing but blue skies and desert everywhere else and I went from great fps to a massive FPS hit, then I regained my usual fps, then the screen went black and the heavy breathing came over the speakers as if I was in a hard g turn, which I was not. What happened next was a screen telling me that DCS had crashed and if I would allow it to collect data for a log to be generated.

 

The log is attached here.

 

This did not happen to me in the previous version of 2.5 open beta just a couple days ago before it was updated and I had way more combat action then just a few tanks to my 9 o'clock.
