Problem with VR preview

Hi. I’m using a GTX 970 and an i5 2500k (overclocked to 4gz), 8gb DDR3, so I assume I’m pretty borderline as far as recommended specs go. As for the project, I was referring to the “first person” blueprint on the projects tab (with starter content). In the VR preview of that blueprint I noticed the lateral movement of the gun was very jittery, so I ran the oculus debug tool as an overlay to see the frames per second count (45). I also noticed the “dropped application frames” was in the red and rising at a very high and steady rate. All seems okay in apps and games outside the editor, so I’m not sure what’s going on. Cheers.
