Vive locked at 60 fps
When we run the VR preview in editor for the first time with our Vive, the framerate is solid at 90fps. Trying to run the VR preview in editor a second time results in the frame rate getting locked at 60fps. Even if no changes have been made to the scene. This means we get one good preview in editor before having to shutdown UE4 and restart it.
We've checked with and without the "smooth frame rate" enabled, and toggled vsync on and off in our Nvidia graphics settings.
All builds are locked at 60fps. Is it locking the framerate to the primary monitor? Any ideas would be appreciated. We're running a beast system with a 980ti.
Thanks in advance.

I am happy that you were able to find a workaround for this issue. I have written up a report ( UE-21310) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your time and information.
Make it a great day

I experienced the same issue. The cause is most likely that unreal editor overlaps the second screen when in fullscreen, as explained here: http://steamcommunity.com/app/358720/discussions/0/523890681427232040/
Compositor isnt fullscreen then -> 60fps lock.
A workaround is to place the second screen below and to the right of the first:
If the problem still persist make sure that the preview window on the primary screen doesnt overlap when opened.
