If it isn't already on your list, please consider a way to allow the VR Compositor to (quickly) invoke a chaperone warning if the application hangs and the user encroaches on a boundary.

Are also you considering a watchdog timer to kill off an unresponsive window owner? As one who has played Source games and had to fight my PC to regain control when the game locks up, I know that a watchdog would be even more appreciated when I've got an HMD on.

I considered asking for multi-headed HMD support, but the stack of problems seem to outweigh the benefit.

Have you yet considered how the chaperone is going to handle the position of multiple users in the same physical Lighthouse coverage zones?

VR Compositor:
"Simplifies handing off from one application to another without full screen context changes by owning the window on the headset?"

Great function; needed. But was this meant to have a question mark on the end?

I thought about it some more. I had Vsync forced on in my Nvidia Control Panel -> Manage 3D Settings. (We should be forcing it on, right?) I turned it off. The amount of strange jitter decreased dramatically, although a smaller jumpy behavior still remains.

Cool

Went to Rift Extended Mode. HelloVR was displayed on my main screen and the Rift. The tracking looked good on the desktop screen, but inside the Rift, it had a jumpy/jaggy quality that was not seen on the monitor. Exited cleanly. Tried SteamVR (which only displayed on the Rift). It also exhibited the jumpy/jaggy behavior. Added -compositor launch option for SteamVR but it did not seem to help either application.

My mistake on HelloVR. I signed up for the Steam beta, not the SteamVR beta. That problem is solved.

Ran HelloVR with Oculus DK2 on OVR SDK 0.4.4 in Direct Mode. Image appeared on my main PC screen and not on the Rift, but tracked very well. Upon exit, was presented with a crash dump.

Crash dump on exit (with escape key) is repeatable.

Just so I understand this correctly, no developer SDK or API update is available, this only updates the Steam client?

@A Lone Gunman - Try running with -compositor (right click, properties, set launch options)

I do hope that the Source SDK 2013 Multiplayer gets some of this VR love because some of these features sound like what I've been waiting for to make my Source-powered 3D virtual desktop more VR friendly with its application launching!

Will current Valve games like HL2 and TF2 continue to be updated with this?
