Drop problem in air combat

About 2-3 months ago I deleted and reinstalled the game. My computer’s specifications are the same. All my drivers are up to date. The fps is between 200-250. Before deleting, I did not have this problem. I could play comfortably and fluently. Now, when I reinstalled it and enter air battles, the game becomes unplayable when in close contact with the enemy. I experience sudden fps drops. It’s starting to become annoying. I tried all the graphic settings. I turned the graphics card features (Ray Tracing & DLSS) on and off from the lowest to the highest. It’s still the same. Is there a solution for this?
