If you're wondering why the Oculus Rift only supports Windows PCs at launch, Oculus co-founder Palmer Luckey has the answer: the current crop of Macs simply aren't powerful enough to deliver a good virtual reality experience.

Speaking to Shacknews, Luckey said that to introduce Mac support for the Oculus Rift, Apple must first release a computer with enough graphics horsepower for VR. "If they ever release a good computer, we will do it," he said.

Luckey went on to state the reason why Macs currently aren't up to scratch for VR. It basically comes down to the fact that Apple "doesn't prioritize high-end GPUs", so even when you buy a $6,000 Mac Pro with AMD FirePro D700 graphics, "it still doesn’t match our recommended specs".

Due to a lack of high-end GPUs in Macs, Oculus doesn't want to support the platform as customers wouldn't be able to play the majority of VR titles at a respectable level of performance. However if Apple decides to integrate high-end GPUs "like they used to for a while back in the day", Oculus is more than happy to support Mac.

This isn't the first time Luckey has aggressively stated that low-power PCs are not suitable for VR gaming. Earlier this year, he said that "your crappy PC is the biggest barrier to adoption" of virtual reality technology. Until high-end graphics hardware gets cheaper, it will be very expensive to set up a high-end VR experience like the Oculus Rift provides.
