NonVR windowed + Direct\Extended VR mode in the same build?

Which Unity version are you using? If you update to 4.6.1, D3D11 exclusive mode should still allow you to run windowed. You'll also need to rename OVRManager.Start to "OnEnable" to allow toggling of VR after the app has started. Then you can just disable the OVRCameraRig GameObject and enable a plain Camera GameObject without VR support. If you can't upgrade, you can still write a script that disables PlayerSettings.d3d11FullscreenMode when not using VR.

Ah! I'm in 4.6.0 I'll update :D

Unfortunately, 4.6.1 did not solve the issue.

With OVRManager disabled and D3D11 Force Exclusive mode enabled, the game still launches in full screen. Changing from fullscreen to windowed mode causes the game to lock up, where as in 4.6.0 it just stayed fullscreen.

Is there something I'm missing?

That shouldn't happen. Is there an error in the log? You can prevent the game from launching full-screen by disabling "Optimize Builds for Rift" in Edit > Preferences > Oculus VR.

Ok, what's really weird is, that's already unchecked.
I'll try to reproduce it and see if anything is in the logs.

I've tried it in all kinds of configurations. Changing resolution in non-vr mode with force d3d11 causes the game to lock up. Specifically, it no longer accepts input, is stuck in fullscreen with a black or sometimes frozen screen, with the in game music still playing in the background. Pressing alt-f4 does nothing. Alt-tabbing makes it even worse, as i can see my desktop but can't interact with anything. I have to hook up my second monitor, ctrl-shift-esc open the task manager and win-arrow key it over to the second monitor to close the program there.

There is nothing in any of the log files, everything there acts as if nothing went wrong.

To run the game in VR mode, you need to enable OVRManager and have users run _DirectToRift.exe. To run in non-VR mode, disable OVRManager and have users run the plain binary. If you're using the latest version of Unity and the Oculus integration, mode switches shouldn't cause black screens or hangs if these two settings match up. It sounds like you are getting a graphics driver crash, which could happen if OVRManager was enabled when it shouldn't be. But there are a lot of reasons the game could hang in non-VR mode.

Okay, that's what I've been doing, I was hoping the game could also run in extended mode, but it sounds like it just can't. Maybe there is some kind of hardware limitation here? But I would really like to see a single binary run extended VR and nonVR modes someday.

As for the other lockups I'll try updating graphics drivers and test on a few other machines and see what happens.

Hi guys :)

If you can't upgrade, you can still write a script that disables PlayerSettings.d3d11FullscreenMode when not using VR.

How it can be if PlayerSettings is Editor class ?) Is it possible to switch mode in runtime (single exe for VR/Not VR) after OVRDisplay.isPresent already checked? Thank you.

To disable d3d11ForceExclusiveMode go to OVRShimLoader.cs and comment code:
PlayerSettings.d3d11ForceExclusiveMode = useExclusiveModeD3D11;

After this your app will launch in windowed mode.
