VR Launching Even In "Non-VR" Mode

[The Horror Network]

Hey,

So I do have an HTC Vive hooked up to my PC, but I wanted to just play the non VR version. I select the first option when launch is initiated, which is non-VR, but yet Steam VR still initiates when the game launches? How can I stop this?

Hello!

We cannot seem to reproduce this with our Vive kits, we can suggest you try the following options.

In your Steam Library, right click on the title and select "Play Game" there should be a warning that shows up saying that it supports VR Natively, then you press okay and the game should start in Non-VR Mode.

If that doesn't work, you can add "-platform None" as a Command Line in the game properties which you can find when you right click and select properties.

Let us know if any of these work.

Thank you for your reply.

I tried both options, and while the game will load as the desktop version, it still launches my SteamVR; which thus enables my lighthouses, and has the SteamVR box at the bottom of the screen:

I found a fix. For anyone else having this issue, it's not the game (I figured as much), it's Steam VR:

1. Boot up SteamVR
2. Go to Settings
3. Go to Developer
4. Untick the box "Start Steam VR when an application starts"

There seems to be a semi-hidden option in the developer settings in UE4-based games that will cause even non-VR titles to trigger VR, especially if the aforementioned option is enabled. It's easy for devs to miss. More detail in this thread.

I've had completely non-VR games trigger VR, but with this setting disabled, it shouldn't happen again.

Hello again,

Happy that you found a fix!

Very interesting that it somehow manages to force into VR, we'll make a note of it and see if we can do something on our side as well to stop that.
