Oculus Sample Framework for Unity 5 Rift Executable V1.0.0

I've been experimenting with the example program from the download page:
https://developer.oculus.com/downloads/game-engines/1.0.0/Oculus_Sample_Framework_for_Unity_5_Rift_Executable/ 

Can anyone tell me if this example executable is only meant to run against 'Oculus Runtime 0.8.0.0'?
I can't get it to show in the HMD if I remove the 0.8.0.0 and install the new 'Oculus home' app / Runtime 1.3.0.

For me, the example executable worked perfectly on runtime 0.8.0.0, very smooth and no judder, however when I build the example from sources at:
https://developer.oculus.com/downloads/game-engines/1.0.0/Oculus_Sample_Framework_for_Unity_5_Project/  
(using the 1.3 version unity plugin and utilities) the result only works with with runtime 1.3.0, and performs very poorly (low FPS and judder). 

I'm using a DK2 and GTX 650, so maybe not the ideal spec, but the "Oculus Home" VR scene runs perfectly. It seems odd that the same example would work perfectly for me on the old runtime and badly on the new one. Does this mean the new 1.3 runtime requires a higher spec graphics card than the 0.8.0.0 version?

Would it be possible for someone at oculus to update the https://developer.oculus.com/downloads/game-engines/1.0.0/Oculus_Sample_Framework_for_Unity_5_Rift_Executable/ to target the latest runtime?
As least then I can confirm I am building the project correctly.
