Need Guidance on GearVR and Unreal 4

[aussieburger]

So, I got scene rendering without gamepads and view weapons, made crosshair small and blue.

For whatever reason, this basic scene causes motion sickness

If I pull Gear VR away from my face, I get less motion sickness. I don’t know if performance sucks and below 60 fps, or if async timewarp doesn’t work, or in-game FOV / IPD are off, or all of the above. I never had this issue with test scenes in Unity

Is there a way to profile test scene in UE4 and see timings on CPU/GPU and fps ?

Do you know if there are settings for virtual IPD? What would be the correct value for Gear VR ?

Any idea if UE 4.10 has async timewarp working?

Is there a way to set render scale?

Is there a way to adjust MSAA and anisotropic filtering values ?

A quick google will give you most of those answers - especially important is the FPS command: stat fps which you can start on begin play via the command execute node. MSAA is on by default and not configurable (you don’t want to turn this off anyway every scene looks horrible then ).

So I guess you noticed now that the default scene is not compatible for either mobile or mobile VR (no way you get 60FPS on that - it has very complex materials, lighting & postprocessing and we are using a mobile device afterall!)

I would highly recommend starting with a simpler stripped down scene like:

and slowly adding to it to see which UE4 features the GearVR can support at 60FPS and which it cannot
