Texture / FPS issue

Hello all,

Ive been having this issue and recently I noticed that pretty much happens everytime I get fired upon by a SAM. As soon as my radar starts beeping my screen freezes for a second, my screen turns fully black (i can still hear ingame sounds) and "de-freezes" resulting in world, cockpit and some other textures turning black. Also, my FPS drop massively.

In single player it rarely happens and when it does its not a problem. I fix it by alt tabbing once or twice and Im good to go. In MP on the other hand, it becomes a problem, considering im being fired upon.

Thanks in advance. :)
