Enable VR causes performance issues?

So I’m bumping into errors while using the WebVR video tutorial. It’s freezing my browser intermittently.

I dug in a bit and found that the 360 Image tutorial, which has similar camera logic, does not present issues. So after trying to replicate the project in search of the script causing problems, I came down to the Enable VR option within the rendering dropdown in the project settings.

With Enable VR (the drops in green are freezes)

Without Enable VR (of course, once Enable VR is off a bunch of other things stop working… but the freezing is gone)

Any thoughts?

Is it just the setting? I did a quick test from forking the 360 camera tutorial and just ticking the option. No freezes on Mac and Chrome.

Is there anything else going on in your scene? I’m assuming video playback?
