After the last update, I started an instant action with the F-18 module.
During the maneuvers performed in flight, I noticed in particular that when turning to the right or left, there is a drop in FPS, from 60 to about 20/25.
I also tested with another module (F-16) and the same thing happened.
Before the last update I have never encountered such a problem, especially in single player.
I am attaching the Dxdiag.
