Oculus Rift DK2 and UE4 4.3:problems with Oculus Runtime 0.4

Hey guys.

As many of you recently figured out DK2 and UE4 4.3 do not work together if Oculus Runtime 0.4 is installed.

We apologize for the mess. I want to confirm that UE4 4.3 is indeed DK2-ready. The problem is the new 0.4 Runtime that unfortunately is incompatible with 0.3-based apps for now. We are working on resolving this issue right now, as well as preparing a new integration of UE4 and Oculus SDK 0.4.

As a workaround for now - you should not install 0.4 Runtime while you use UE4 4.3. Instead, you'll need to install a DK2 camera driver, download link:
http://static.oculus.com/sdk-downloads/Oculus+VR+Camera+Installer.exe
(Note: you will need to uninstall this driver later when you decide to switch to 0.4).

If you already have installed 0.4 Runtime then you may either uninstall it and install the camera driver from above, or you need to disable the OVRService by performing the following steps:
1) Remove or Disable the "Oculus Service Scheduler" from the Windows Task Scheduler: "Start" button -> "Task Scheduler"
2) Switch display mode to Extended mode or uninstall the Oculus Display Driver;
3) Remove "OculusConfigUtil.exe" from Programs -> Startup (For example, C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup).

    I finally managed to get DK2 more or less working on Unreal 4 but I am having a major performance loss as soon as I activate VR mode.

    Even when I use a blank first person shooter template scene:

    non VR mode : 200+ fps (frame 4.92ms, game 1.16ms, Draw 4.53ms, GPU 4.92ms)

    as soon as I use "stereo on" it just manages to get to 75fps (Frame 13ms, game 1.1ms, Draw 2.1ms, GPU 13ms)

    but at some points in this simple scene it drops below 75 causing the judder effect.

    When I raise screen percentage a little bit : HMD SP=175 It drops to 55fps (Frame 17ms, game 1.4ms, Draw 2.2, GPU 17ms)

    I have to lower HMD SP to 100 to get smooth 75fps..

    This performance loss seems unreasonable, especially in such a simple scene (when I load more complex things it much much worse & I need to lower HMD SP to 75 to get acceptable frame rate in the DK2 but then I lost all detail in the scene.)

    My system :
    I5 3.5Ghz
    8gb RAM
    Geforce GTX780

    Anyone experiencing the same issues?
