I was able to get Kings and Heroes working using Vorpx.
Kings and Heroes is an fps co-op dungeon crawler on steam early access.

I am playing it using an I73930k, Win10, 64 gigs ram, GTX 760 x 2(no sli for U4 game), SSD, Custom Xbox 360 mappings using Pinnacle game profiler.
With my under spec machine i can run the game in my DK2 at 45 to 65 fps.(no VR sickness for me)
