When I connect the Vive, or if it is already connected when I launch, Unity will freeze up and become completely unusable. If I unplug the Vive it goes back to normal and is usable again.
I’m using Unity 5.3.5f1 on Windows 10. Have the latest drivers 365.19 for my GTX 970. I have version 1.1.0 of the SteamVR plugin. I have a pair of Dell U2413 monitors that are connected by Display Port. The Vive is connected by HDMI.
The Unity project is as basic as possible. Just a SteamVR Camera Rig and a Plane.
I think my problem was caused by bad USB drivers. After I started getting BSOD several times a week, I decided to do a completely fresh install of Windows 10. This fixed my problem with Unity.
And I am also able to play Windlands now, which was previously not possible. It was lagging so much that it kept jumping back to the “This is Real” lobby, then back to the game. So I’m guessing that maybe Windlands was made in Unity?
