I'm using Unity and I'm trying to hack some positional tracking into the Oculus Go. I'm wondering if there is any way to retrieve the estimated time till photons? That would be important for correctly predicting the HMD's pose.
How much time does the headset usually take from rendering being finished (= "OnPostRender()" being called by Unity) until the rendered image is displayed? What process take place during that time and how can this time be measured/predicted?
Any help is much appreciated. Thank you very much!
