The DirectShow filter chain alone will add you several frames of latency easily. DirectShow is far from a real time, low latency API. The fact that the camera is an USB 3.0 model is a red herring - that only affects how fast it could *theoretically* transfer data but has no impact on the various buffering and processing done once the data are in your machine. > I am hoping that OpenGL applications also benefit from the low level driver > support created for the Oculus and similar VR devices. Even if they didn't, even the plain old Rift DK1 has a sub 20ms latency. So that is certainly not the source of your problem.
