I recently built a new computer to better accommodate the forthcoming line of resource-intensive tech products, namely the Oculus Rift and related VR devices. While my old computer was nothing to shake a stick at, its hardware was not satisfactory enough to produce a consistently smooth experience on the Developer Kit 2 (DK2). The second iteration of the developer headset kit requires rendering a 1920x1080 display (960x1080 per eye) 75 times per second or else latency and lag lead to a jittery and nauseating experience. When the consumer version drops next year the hardware demands will be even greater.
With my latest PC upgrade (Geforce GTX 980 TI, MSI Z97 Gaming 5 motherboard with an Intel i7 4790k CPU, 32GB RAM, Samsung SSD 840 Pro, Sound Blaster Zx) I made the sudden, albeit fully expected observation—none of these new components provided any Windows XP support by the manufacturers. After all, Microsoft itself ceased mainstream support for XP way back in 2009 and officially declared it to be 'end of life' and fully unsupported in April 2014. It makes zero sense for any manufacturers to waste additional developer resources maintaining support for such an archaic and unsupported operating system, even as millions of diehards still cling on.
