DK2 screen freezes shortly after starting playing on Unreal 4.8.x

AtsK · July 19, 2015, 1:08am

Whenever I try to test one of my projects (using a custom player controller with a custom camera manger(that has the follow HMD orientation flag enabled)) in VR the display tend to freeze. I do not get an error message.

The game itself continues functioning: although I can not see anything change on screen I can interact with it: open the console and disable stereo rendering and the game works just fine after that but reenabling it crashes the editor/game. And that even after restarting the editor.
Maybe it has something to do with the tracking, but idk…

And If I want to run the game again in VR I have to stop and restart the Oculus Runtime (V.0.6.0.1). Because if I don’t restart the runtime I get the following hard crash of the editor:


Unknown exception - code 00000001 (first/second chance not available)

Which graphics card, which driver version?

AtsK · July 19, 2015, 9:00pm

Nvidia GTX970, driver version 353.30

Ben_Cykyria · July 19, 2015, 11:21pm

Downgrade driver to 350.12 then it should work (see Oculus release notes)

AtsK · July 20, 2015, 1:58pm

It indeed looks like that downgrading the drivers did the trick. Thank you so very much
Will try to be more observant with release notes from now on.

Ben_Cykyria · July 20, 2015, 7:12pm

you’re welcome

AtsK · July 21, 2015, 6:25pm

Grr, I was wrong the issue is still here. Sigh
Will try to investigate further than.

Edit might have something to do with Leap motion in this instance.
