    Hi Guys

    Newbie question1, for raytracing to work, should my main monitor I use the editor on, be connected to may raytracing enabled card, or can that card be my secondary card without monitor connected? (I have a Gtx 670 as my primary and 1080Ti as my secondary)

    Newbie question2, For raytracing, can 2 X RTX2080Ti's be used in SLI to double up the VRAM, or is SLI not supported currently?

      Hello! Answering both questions, UE4 doesn't support Dual cards yet, althought they do are looking to implement that feature in future versions!

        Please see attached pics for tests using RTX. Are these Post Process Volume Settings correct for Glass Translucency and Reflections? Any suggestions on where I can improve? Thanks

          Is ray tracing supported by Intel integrated graphics cards at all? I've changed some of the Ray Tracing settings in the Global Post Process, and see observable results. Yet when I enable ray tracing in the project settings, I can no longer open the project since it crashes before it completely opens. When I looked at one of the crash logs I had for a project that I turned ray tracing on for, it had errors regarding screen space denoising.

            Currently realtime raytracing is a feature only supported by NVidia RTX graphics cards under Windows 10 (both graphics cards' drivers and Windows release needs to meet a minimum version for it to work). No AMD or Intel graphics cards support the feature for now, not even on Macs or Linux.

            PS: It should not crash thou.
