UE4.8, Oculus Runtime 0.7.0.0 beta.

In non stereo mode, game is flying. When I turn on stereo mode, the game hits 75 but drops to 60 every second for a flash. Makes game stutter every second. Any ideas what’s going on? Have searched and cannot find anything on this.

Hi there,

had the exact same problem a while ago.Did post that on the Oculus Forum, but they ignored it basically.

The only thing which fixed it was changing the HDMI port on the GPU (depressing, but true).
