Subject: Set zero swap interval in the OpenVR combiner
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=eef7ce73069a71a4001442fc54010dc08e74ca1a;p=libs%2Fvr.git

Set zero swap interval in the OpenVR combiner

Otherwise the swap_buffers from rendering the mirror view will interfere
with submitting VR frames.  The OpenVR library internally syncs to the
HMD's vertical refresh.
