This is happening for me on both profiling and standard branch

This is the video I have of it happening to me in the A-164. Happens in other AA armor vehicles as well, and happens with or without mods. Also pardon the titles cutting off.

I experience the same problem with an upper-mid range PC that experiences no lag or other issues in singleplayer or multiplayer. This is disappointingly not addressed yet, two months later.

I've attached the files requested.
