Here is a video showing what the issue ishttps://youtu.be/n5ngEzZSKH0
I'm trying to release an update to Vanguard V but perforance has become a real issue. The game runs at 150fps on my laptop but the framerate tanks when I touch the Oculus headset. I get these nasty yellow spikes and the FPS tanks to the 50s, even on my desktop (980 GTX TI). I then created a new scene with nothing but a camera and the default Directional Light. The framerate goes into the 800s until I touch the headset. It then tanks again to 90-100fps. This is an empty scene.
Now, if this is by "design" it has made it very difficult to isolate any real issues in the profiler. Any help would be great.
