Change fixedDeltaTime for Meta Quest

In my app I need to run phyics faster than the 70Hz framerate that is applicable for Meta Quest. I tried setting Time.fixedDeltaTime in my script, but it does not make a diffrerence. FixedUpdate runs only every 14 ms.

I looked at the OVRManager script, but can’t see any settings that will allow this.

I also looked at the Quality settings, but nothing obvious there either.

How can I achieve a higher physics rate for the Quest?

Setting Time.fixedDeltaTime is the correct way. Also, setting the value in “Project Settings > Time > Fixed Timestep” is also valid.

If changing the property doesn’t have any effect, then the value is being overridden and enforced by some other script. Maybe there’s some option in the XR settings about this? I’d also try asking in the XR forum/tag/category/whatever-is-now.

Yeah, I was hoping someone could tell me if such an override exists and can be disabled.

I had the same issue with SteamVR and there you do have a flag ‘Lock physics rate to framerate’ and if you disable that flag you can set fixedDeltaTime to whatever you want.
