How to launch Vive/Index/WMR/Cosmos vs Rift vs Monitor versions

[DrashVR]

When you right click on Titans of Space PLUS in your library, you will see some launch options:

For Oculus Rift / Rift S using the Oculus Runtime, choose "Launch on Oculus Rift in Other VR Mode".

For HTC Vive / Valve Index / Windows Mixed Reality / Vive Cosmos / Oculus Rift CV1/S in SteamVR mode, choose "Launch App..."

To play in 2D on your monitor, choose "Launch on Monitor"

NOTE: The above still holds true, but as of the new v2.5 Update, if you happen to accidentally use a Rift in SteamVR mode, that is no longer going to be a terrible experience.
