Vertical Sync in Vr

Hi there!
I’m having an issue with vertical sync and Fps cap when i run a compiled experience.
When i’m in Vr mode i can’t uncap fps or enable Vertical Sync and it runs at 35 fps with flickering.
When i run without the oculus it unlock and runs perfectly at >70.
Anyone with the same problem?

Thanks!

Yes, I do. It is connected with shaders, imho. I did something that disable them and problem was solved.
and now I am trying get some shaders back, but with no success =D
