The first time I use VR Preview for the Vive after opening 4.9 fresh, I get a smooth 90fps. However, the second time and thereafter using VR Preview, the frame rate is locked to 60fps and the display is very juttery. This makes development very difficult, since closing and opening the editor on every test is a horrible iteration loop.
It seems like I’m not the only one seeing this problem (http://steamcommunity.com/app/358720/discussions/0/520518688938304673/). Has anyone else experienced this and found a solution?
