[Tranq rifle huge fps drop]

I got a huge problem with the tranq rifle since the newest update.

My game runs at 140fps on highest settings, no problems there. But if i equip the tranq rifle, any camera movement causes huge fps loss. If I don't move my mouse, the fps stays at 140, but constantly moving the camera reduces it to 3FPS. Literally 3. This happens the moment i equip the tranq rifle, doesn't matter am I on Earth or Orb Vallis. Even if I unequip the rifle, it doesn't fix the issues. If I abort and go to another mission the game works normally again at 140fps. Until i equip the tranq rifle again. How can equipping a rifle have such a huge impact on fps?

Thanks for the map, really helped.

Also, I found 1 more at the cave furthest to the north.
