Unfortunately I wasn't able to make this work with runtime 0.5.0.1. I did get it to display an image in extended mode on the rift, but the resolution of the Rift DK2 wasn't available in the dropdown so no resolution quite made it line up well enough to be usable. I did see the beautiful green alien/plant hand model out of one eye and thought it looked amazing! I would really like to make this work so if you have any ideas for steps to take, I'd love to hear them!
I'm using this runtime switcher to test older apps built with the pre-0.7.0 SDK: https://www.reddit.com/r/oculus/comments/3paivl/rtu_package_to_switch_between_oculus_07_and_05/.
