I’m using the same hardware setup as the OP although I am using the most updated Nvidia drivers (358.50) and Vorpx cannot find the Rift when I try to configure it. I’ve tried DK2 runtimes 0501, 06 and 07. The demo scenes all work fine and many of the demos from Oculus share do as well, but Vorpx simply cannot find the Oculus. No reply yet from support. Anyone have helpful ideas?
