I can't find anything in those logs that stand out as problems, but I just remembered that I had that double vision issue when I was first testing out Valve's renderer that was caused by having multiple cameras in the scene but that shouldn't be an issue here. Can I please ask you a few things?
1) Do you have Steam and SteamVR running before you start the game executable?
2) Do you have SteamVR direct mode disabled?
3) Are you running the game through a Steam shortcut or running it as an admin?
4) What are your asynchronous reprojection / interleaved reprojection settings?
Try running Steam and Steam VR, disabling direct mode, disable asynchronous reprojection, enable interleaved reprojection, and run the main.exe executable straight from the folder.
Thanks for getting back with those details and sorry to put you through this. It sucks that these issues exist but it's better to find these problems sooner rather than later.
