how do we know if daz is using rtcores on nvidia rtx cards, thanks

  • If you are using an RTX GPU with the current version of DS you are using the RTX cores, though I'm not sure how (other than speed increase) you can see that.

    rtx rendering is supposed to be only available in daz 4.12 with nvidia studio drivers but when i switch from nvidia studio drivers 431.86 to nvidia game ready drivers 436.48 i render at the same speed so it seems the rtx2060 on my omen 15 is not using rt cores but regular cuda cores, any idea how daz or any nvidia monitor utility can confirm that i  am using rt cores ( gpuz gives no monitoring info on rt cores ) thanks

  • Game drivers should not be blind to RTX, where does it say that Studio needs the Studio drivers (rather than their being recommended)?

  • I used the game drivers when the beta added RTX. I saw asignificant speed up on my 2070. As far as I'm aware the rtx cores work in the game drivers, otherwise they wouldn't work in the games where it is enabled.

    In my case, I compared an identical render pre-update and post-update and I saw a 25% cut in render time, so, for me and my rtx 2080, that's persuasive enough.

    They're all just different snapshots of exactly the same driver. See this post for a longer explanation. And see this post explaining what to look for in the log file for indications of RTCore usage.

    when you say "significant speedup" is it 25% like this other user or closer to the 10x theoretical peak speedup nvidia promised ? either nvidia lied either daz studio rt cores code path is poorly coded

    The ten times (ddi they actually say that?) would be for the ray tracing operations - Iray does a lot of other things too on each pass so the overall gain will not be the same as the gain for ray tracing.

    sure we never get to theoretical peak performance but i was hoping for at least a 2x speedup in real world usage so your speedup was closer to 25% ? thanks

    25% (roughly). 10x would be just on doing the raytracing of light. iRay does a lot more to produce a render so all that stuff still has to be done by the CUDA.

    here is the quote on nvidia/daz annoucement: it did not look like 25% faster to me : "Turning ‘RTX On’ with NVIDIA RTX Studio laptops will give our users a huge performance boost. — Steve Spencer of Daz 3D"

  • 25% is a huge boost. Add inthat this version of iRay is just plain faster than previous versions and that Turing cards have more and faster CUDA than previous generations and it adds up to a significant increase in performance (my 2070 renders some scenes faster than my 1080ti).

    As someone who produces a lot of images for my VN's the speed increase has made it difficult if not impossible to keep my machine rendering 18 to 20 hours a day as it was before 4.12.
