So most of us did the SteamVR Performance Test. Have you guys did the Oculus Rift Compatibility Tool test? Some people also call it Rift PC Advisor.
I've been reading on Reddit and the Oculus forums about people having issues with the USB 3.0 controller on the motherboard...
SteamVR Performance Test is free and on Steam of course. It seems to be GPU bound also. Give it a go and see how you do. ;) I didn't use the new Vulkan driver if that matters.
