Hi, i just tried to build nVidia fork of unreal sourcecode to try out VR Works, so i:

  • cloned https://github.com/NvPhysX/UnrealEngine.git repository, branch VRWorks-Graphics-4.16
  • ran both .bat files correctly as in instructions
  • since the company want to keep everything on network drives for backup/safety i applied “patch” described [here][1] to build from network drive, all fine
  • first build gave me problem related to SetPipelineState so applied “patch” described [here][2], all fine

Subsequent build give no errors, but when i run UE4 (outside VS debugger) it show up start screen and when starting loading content it crashes (at 0% loading) with following error.

I’m not sure about it, but i think problem can be related to video/graphic stuff, WindowsD3D11Device make me think about Windows Direct3D 11.

Any help is appreciated, thanks in advance.

Graphic card: nVidia Quadro 3800, drivers just updated to 342.00

OS: Windows 7 professional 64bit, build 617601 SP1

System ram: 16GB

Ok, found the problem.

Tried official clean UE4, and opening any project give me following error, trying compiled nVidia fork on another pc with different graphic card and get no error, it work perfectly.
