[VIVE] All character animations are very slow only when previewing in VR.


I have a game where several characters are moving around the scene using animation blueprints with blend spaces. When I play it in the viewport, everything runs fine and the animations work at the correct speed. When I plug in the Vive and run it in VR Preview, however, all the characters are moving very slowly (looks to be about half speed). There is also a part of the game where some of the characters grab pieces of a wall and throw them into the air (they are physics objects) and they hit the ground. In the Vive, even these objects are moving very slowly when thrown into the air.

Any idea what could be causing this? This problem does not occur in the Rift. Only in Vive. Any help would be greatly appreciated. This is driving me nuts. Thanks guys.
