Trembling image (Oculus DK2)

Hi guys

Sorry for bad english.
I use Oculus DK2 and "Extend Desktop to the HMD" Display Mode. The DK2's Couch Knights demo runs very smoothly. But if I create a my project (first person BP), then it have micro shuttering (jitter). when I turn my head, the apparent small twitching. How to get rid of shuttering (jitter)?

    This comes up every day, and there are tons of threads (just search for "judder" or "jitter", two different things).

    If you are using Unity, you may want to force DirectX11 to be on. You can also try setting your monitor to 75Hz refresh rate (maybe at a low resolution) or making the DK2 the primary display.

    The biggest contributer to low frame rates in UE4 at the moment is post processing. Copy the post process node from couch knights and turn off real-time shadowing, then most of the judder will disappear.

    Yes, if Copy the post process node from couch knights and disable "Cast dynamic shadow" (for "DirectionalLight") then works smoothly. Can we do without turn off "Cast dynamic shadow"?
