All unity builds running at 60fps?

Has anyone been able to get their project to run at 75fps?

I've tried running both a build of my game and a build of the unity tuscany demo on the DK2, and they both lock to 60fps instead of 75. I've checked the refresh rate settings in both the windows monitor preferences and in the nvidia control panel, and they both say 75Hz. Is there some other setting that I've missed?

Worth mentioning that it's not a performance issue, if I turn off vsync they both run at several hundred frames per second.

Other info:
Windows 8.1 x64
DK2 is in extended display mode
DK2 is secondary monitor, 1920x1080, 75Hz
Unity is set to vsync on every vblank
Using Unity 4.5.2p2

    Okay I've found a workaround. Making the Rift the primary monitor Unity now uses 75hz for VSync. It's not the ideal solution cause programs starting in Window Mode coming up on the rift but it works.
    Also someone on reddit mention the software "Radeon Pro" to force the graphics card into 75hz vsync but that didn't seem to work for me.


    About a year ago I've created a simple application called ForceRift that hides all displays except the Rift's from an application using some API hooks. This to make applications where you can't specify the monitor to start on to use the Rift's. That worked pretty well (for DK1), so maybe you can try using that?

    It doesn't have DK2 support (because mine's not there yet), but the source code is included, so that should be easy enough to hack in yourself.
