    It doesn't really help, but I ran it on a Titan X. Can run on a 970 later (Need to plug it in). But the results were:

    VXGI diffuse and specular disabled: 300 FPS (3.3ms) when standing at one end of the hallway and looking down all the way (default player spawn)
    VXGI diffuse enabled and specular disabled: 110 FPS (9ms) in the same position
    VXGI diffuse and specular enabled: 80 FPS (12.5ms) in the same position
    Interesting. The Titan X should only be roughly double the speed, where you're getting nearly triple. When you get the chance, could you post how the 970 does in comparison? I wonder if the extra speed really is because of the Maxwell chip or if it's just a fluke because it's such a powerful card.

      Will do, over the weekend most likely, so if anyone else has a 970, feel free to post results.

        Hi,
        I'm new to Unreal and especially using development build, I'm experimenting with hairworks and it's great so far but I wonder how hard it would be to get transparent tip as there's already rootAlpha fallof?

        I also wonder if the one directional light limitation is just for performance or if there's an issue and we'll just have to live with it for a while?

        thanks

          Transparent tips would have to be something that NVIDIA does at their end, don't think the HairWorks API supports transparent tips either.

          The one directional light is just a limitation at this time, I suspect that they will get more lights implemented at some point, probably grabbing 4 or more of the closest lights and averaging out the results or something along those lines (Thats just a guess on my behalf, I do not speak for NVIDIA, so they may have completely different ideas).

            For what it's worth, here are my results with the SciFiHallway on my 970M:

            32-34 FPS VXGI diff + spec
            40-50 FPS VXGI diff
            locked 62 FPS (maybe vsync on?) with only direct light

              Mike.Skolones , are these github links supposed to work??

              https://github.com/NvPhysX/UnrealEngine/tree/HairWorks

                Those links work just fine. Follow these instructions:

                  Does "https://trello.com/b/gHooNW9I/ue4-roadmap UE4 Roadmap -> Rendering -> Hair/fur shading" mean NVIDIA HairWorks?

                    Hi

                    Is there a way to get the Flex water to look the same/similar as in the stand alone demo rather than as beads?

                    Comment


                      Any idea of a rough estimate of maybe when we'll also have a GameWorks VR branch?
                      I would really like to see it in action.

                        Example map "flexFluidSurfaceTestMap".

                          I hope they eventually do- extremely cool stuff! Keep up the great work

                            GalaxyMan, just wanted to point out the minor issue that the VXGI documentation in your Doco folder (at least the PDF) isn't the latest one which was updated with multi-bounce info.

                              It appears they only just recently updated the VXGI doco, this is why mine is not up to date. I have grabbed the latest version and am updating my repo. Thanks for the heads up.

                                Huh. Did not expect a mobile GPU to outpace my desktop GTX 780, especially by that much. And yeah, the 62 FPS is with framerate smoothing enabled, it caps it to that by default until you disable it.

                                Might be time for me to invest in a 980 Ti.
