Stuttering on surface book 965m

Hi!
I've recently purchased the HP mixed reality headset and set it up successfully on my surface book with performance base 965m.
However, I noticed stutter in the cliff house and other steam vr application as soon as I turn my head and its very nauseating.
I've tried rolling back to the previous windows build, stopped insider preview, installed recommended nvidia and Intel GPU drivers but to no avail.
However, I found that the stuttering has stopped after I've disabled the nvidia GPU in device manager and did a restart. Enabling the nvidia GPU introduced the stuttering again.
I wonder if there's any "optimized drivers" or any fixed to this issue as I have to disable the nvidia driver for MR to be usable for now.
Any help is greatly appreciated! Thanks!!
