VR needs to at least match the bleeding edge in graphics, which is desktop GPUs. Those desktop GPUs have large wattage and cooling demands. Therefore wireless VR headsets must use the mobile or laptop versions of those GPUs, which perform worse than the desktop equivalent. On top of this VR needs to draw the same scene twice (one for each eyeball). I cannot see how VR will ever overcome this with current hardware. They need to be able to put a desktop GPU in the wireless headset without needing to power it from AC, and thats just for starters because didnt Carmack say we need something like 240hz and 4k+ (for each eyeball) for indiscernible photo realism? Id say were maybe 10-20 years away from just having the GPU power to do this, let alone making software for it
