Are Windows Mixed Reality requirements that much higher than Oculus Rift ones?
Because I have a cheap Bulldozer CPU with a Radeon 470 (that I thankfully bought just before the mining craze), and 95% of games run well !
(And the remaining 5% run so poorly, with similar "required minimums", that I'm suspecting that their developers just didn't bothered to test their games with Bulldozer CPUs!)
SteamVR benchmark even says that my PC is "VR Ready!" : https://steamcommunity.com/sharedfiles/filedetails/?id=1116639906
