Is anyone getting framerate loss sporadically, or when certain things happen? In the VR test, firing a lot of raven missiles seems to cause a framerate drop similar to how the Vanguard did just after GU2, though not as severe, though I can't replicate 100% of the time, so it might not be that.
I also get a lot of instances where I get a frame rate loss for no perceivable reason while I am alone. Doing the same actions in game with a hundred people around me, don't get the same drops. Wouldn't worry about it too much. Possibly using debug code and doing a lot of background checking that's not necessary once it's live.
