FSAddon LLBG Frames drop

Hey mates,

I'm using the nice Tel Aviv scenery and just made a flight in/out. But everytime I'm experiencing the same problems with the frames.

When approaching (doesn't matter which RWY or approach) or when departing frames going down. It's not a slight show but you sometimes see it.

Normally having locked 40fps. But at LLBG they are going down to 15-25fps depending on aircraft.

Is there a change to bring up the frames? Maybe with deleting some useless .bgl?

Thanks
