So far nothing from 0.8 or below (including the official 0.8 sdk samples) will run on 1.3, at least for me. They all fail to init the ovr library. So pretty much everything available before yesterday won't work. I did tick the box to allow untested rift apps.
My dk2 is working with 1.3, the new tuscany demo from the 1.3 sdk works. Well mostly, the audio is broken.
