MiG-21 and the CWG map, lag/FPS drop looking ahead

[Volator]

Is anybody else experiencing lag / dropping framerates when looking straight ahead through the gunsight in the MiG-21 on the CWG map?

I noticed this when spawning in Peenemuende and Neubrandenburg. Looking to the left or right the performance is perfectly fine, only looking straight forward procudes this problem. This only happens in the MiG-21; I compared MiG-29 and Mi-8 and they showed no issues. I also cross-checked with Caucasus map and the -21, no issues there either.

---EDIT---

It's this known issue with the CWG map. Flying to the south improves performance.
