Oculus Go vs Samsung Galaxy S9+ VR performance

Hi there,

I'm currently working on my university final project, creating a VR game for schools.

For the past six months I've been developing for use on a Samsung Galaxy S9+ in a cheap, generic mobile VR headset, and achieving 60fps however one scene is bringing me down to 45fps, not a great experience... lol. I was wondering whether to switch to the Oculus Go, would it improve performance/ maintain the same performance? I heard the S9+ processor is a few generations ahead, but then the S9+ has background processes and wasn't built specifically for VR, whereas the Go is.

Was wondering if anyone had any info on this? Should I make the switch?

Many thanks!
