    Red face New RTX 2080 card performance for iRay?

    Nvidivannounced new Gfx cards with special Raytracin shader cores, the RTX 2070,2080, 2080TI.
    Does anybody know if these raytracing accelerator cores will be used for iRay and how much the Performance improves?

    Default the RTX 2080 Rytracing Cores have no effect on iRay performance

    Info from Forum:
    CPU + GPU: >8 min. How disappointing! With the 1070 it rendered in 3:11 Min.! But I think, maybe the Intel security patches slowed down the performance.

    With DAZ 4.11 Beta, it's much much faster - it uses a iRay codebase that requires at least Kepler Chipset:
    8700K + 2080: First Picture: 0:05, 90%: 0:09, 95%: 0:59, 100%: 1:21
    8700K + 2080 + 1070: First Picture: 0:05, 90%: 0:06, 95%: 0:08, 100%: 0:46

    CUDA 10 had the same performance as CUDA 9. Adding the CPU to rendering tendentially reduces the performance.

    So conclusion is, software improvement has more effect than the new grapphics cards have. The performance also scales good when you add a GTX 1070 to the RTX 2080.
    It's obvious: Currently neither CUDA 9 nor CUDA 10 nor DAZ Studio use the new Raytracing cores. So it's just evolution, no revolution. As I read here in the forum, only Optix will support the raytracing cores, but iRay uses Optix Prime, which only uses the normal cores. It's a pity! Nvidia failed to get the software ready. So we can only hope that it will be soon, but for iRay, nobody commited to yet

    Did anybody from NVIDIA even comment on it yet? I saw Optix 6.0 released last week and was hoping it wouldn't be long before RT was integrated into iRay (at least over the next year or so). I would be astonished if it wasn't a project at NVIDIA if they want to compete in this space. I mean it's a no-brainer. I can well imagine an AMD or Intel competitor arising and people switching to a more hardware agnostic layer like DXR or Vulkan if they don't.

    We showed an RTX accelerated Solidworks Visualize last week at Solidworks World.
    We need a few more weeks to finish this implementation. But it will come this Spring.
