NVIDIA GameWorks Integration

What happens if you put the command in your Consolevariables.ini (on your latest build of VXGI, and please doublecheck you really do work with the latest build just to make sure)
's what I start the editor with when I want to work in VXAO mode:

Consolevariables.ini (UE4vgxibuild\Engine\Config)



r.VXGI.DiffuseTracingEnable=1
r.VXGI.SpecularTracingEnable=1
r.VXGI.MultiBounceEnable=1
r.VXGI.CombineSpecularWithSSR=1
r.VXGI.MapSize=128
r.VXGI.Range=512
r.HBAO.Enable=1
r.VXGI.AmbientOcclusionMode=1


Note you don’t need all of the above but maybe try and see if it helps?
