I'm investigating using an Oculus Rift CV1 for headset reviews of 4K media on Ubuntu 16.04 using RV and Nuke.

It seems the documentation for Nuke / CaraVR is very useful and getting that working out of the box was pretty painless... Nuke's framerate playback when Monitor Out is enabled with the Rift connected is not ideal though - 15FPS from the viewer (30FPS out of Nuke Studio using the timeline) - we need 60FPS though as that's what we're delivering media to the client in. Can't "Monitor Out" of a flipbook either. 

RV was basically a no-go either, as that seems to want separate GL distortion shaders- and even then the head tracking doesn't work so it's basically a worse broadcast monitor. It did seem to play back at the correct framerate though... mplayer essentially did the same thing, once Nuke had been triggered to make the display available for configuration via xinerama.

Has anyone else had any luck (or experience at all, successful or not) with any applications (above mentioned or otherwise) on Linux for 60FPS playback of 4K media through the Rift, complete with head tracking?

At the moment we're testint primarily with the Rift connected directly to the GPU (GTX {9,10}80, it matters not), but haven't had any luck running it through a dedicated output playback device either (BlackMagic Decklink Mini Monitor 4K) as it seems that applications and HMD drivers don't even recognise it as a video device, so won't display any video.
