As someone who contributed to a (formerly) OpenGL-based video player[1], these issues with waiting for vblank and frame time variability on Windows are depressingly familiar. Dropping even one frame is unacceptable in a video player, but we seemed to drop them unavoidably. We fought a losing battle with frame timings in OpenGL for years, which was eventually solved by just porting the renderer to Vulkan and Direct3D 11.
One thing that we noticed was that wakeups after wglSwapBuffers were just more jittery than wakeups after D3D9/D3D11 Present() with the same software on the same system. In windowed mode, this could be mitigated by blocking on DwmFlush() instead of wglSwapBuffers (it seems like GLFW does this too, but only in Vista and 7.)
