Testers of the Quest Pro foveated rendering via OpenXR Toolkit have unfortunately reported a showstopper bug in the Oculus software and/or firmware. It looks like it is not possible to use eye tracking via OpenXR from the PC without disabling the guardian first. This is an unacceptable limitation to release with, because I don't want a bunch of people walking around their homes wearing a VR headset without a guardian, ready to injure themselves (and sue me because I "asked them to disable guardian"). This is not an issue I can fix, this is an issue of the Oculus software.
While my side of the code is 100% ready, there is no way I can release anything until this bug is addressed by Meta.
