vr user - periodic fps loss

[Terzi]

I am a vr user and never had such problem before. No matter if its single or mp mission, the game almost stops every 30 seconds. After getting stuck for a few seconds things flow again.

 

Normally no fps drop, everything is so smooth as it has always been before. But this periodic problem is a nightmare.... Let me know if i can send a file to prove this. Gtx1070 and rift s user.
