At OC6, John Carmack said the Quest could run at 90Hz but they would have to recertify the device with the FCC to do that. Something is telling me they didn’t do that because they didn’t think the Quest was gonna be the next hot item. The Quest sold like hot cakes, as I’m assuming you know, so FB has the money and resources to recertify it.
I’ve made a petition addressed to Facebook asking them to recertify the Quest with the FCC to allow the device to run at 90Hz. If you can, please sign the petition and share it with your friends. Here it is: https://www.change.org/oculusquest90hz
