UE4 Performance issue (Google VR project)

Hello,

I am developing a Google VR project but I get stuttering every few seconds while working in the UE4 editor. The stuttering is gone in the packaged game (testing on mobile is very smooth).

I ran a profiler and I noticed every few seconds UE4 calls “FAndroidDeviceDetectionRunnable” which takes 1000ms of CPU time, Can anyone explain what that is and how to get rid of it?

I am also seeing “FTcpMessageTransport” and “FUdpMessageBeacon” taking up 1000ms of CPU time occasionally.

Anyone have any idea what these are and how to fix this? The longer I work on my project the more often the stuttering gets. I have to restart UE4 to get rid of it but after a few minutes it comes back.

Thanks
