Performance (S-75 on the Position)

[WaffenCat]

Hello comrades and sorry for my English. 

Yesterday I found a performance problem on the map "Cold War - Germany".
When I install the S-75 or Kub (for example) on the air defense position on the map (or outside it) - then at a certain point in time and at a certain camera angle the FPS drops. Very much. A jump from 150-180 frames to 40 or even 25 frames. If I turn the camera slightly at a different angle (see screenshots) - the FPS is restored to values of 170-180. Having turned the camera a little - it drops again. After a few minutes - it can recover itself and the performance becomes stable, as if nothing happened ...

I added the mission here as an example. I am attaching screenshots. 

My configuration: AMD Ryzen 7 5800X3D (4,5Ghz), ASrock Fatal1ty x470 Gaming K4, 64Gb DDR4 3200MHz G.Skill RIPJAWS V, Palit RTX4070Ti GamingPro OC, Samsung SSD m.2 970EVO (970 EVO Plus), ARDOR GAMING Infinity 27 (IPS/1080p/165Hz), Windows 11.

 

Please note that in the cockpit, the FPS is stable, even despite the fact that there are a lot of Phantoms on the station. And as soon as I turn on the F7 camera, the performance drops when I look at the SAM system at a certain angle.
There are no mods in the mission. The textures are standard. At the same time, sometimes the FPS drop is noticeable immediately after the mission starts, and sometimes you need to restart the mission several times. Sometimes the drop appears immediately, from the start, and sometimes a little later. Simulator settings are on the screenshot. I haven't checked with other units, but there may be similar problems. This hasn't happened before. The game version is the latest. 

Opened MSI Afterburner - the video card is loaded at all 12G, as always. Temperature - 50-60 degrees.
Processor - 60-71 degrees, frequency 4450 (no boost).
RAM - load from 45 to 49 gigabytes out of 64.

When the above problem occurs - there are no surges in voltage, temperature, hardware load.
