    SDS stirred my curiosity when he said (I’m totally sold on the new cheif architect rendering engine “raytrace”)

    So i decided I’m gonna sign up and just watch the release on X13 to see what’s new for them and thought this is something that Cadsoft should really consider.

    They changed their rendering engine so that you can make it run the render using the graphics card instead of the CPU. (i know that they are trying to make some CPU capable of matching a graphics card power “i guess you could say” but not sure if that’ll happen)

    They showed the numbers and it looked like it trims the render time by a thousand times (maybe more didn’t figure  it out forgive me)

    The cpu render took 2 hours

    The 2070 graphics card render took 7 seconds. the 3080 took like 3 seconds

    I know they prolly made those numbers it little bit better than it was because they ran a render to show the people and and it took maybe 10 seconds I’m guessing.

    I also understand that the quality of the render might make the time change some.

    But i guess i just thought that this was something that kinda impressed me, because it very obviously speeds up the render if you have the capability to do that. you wouldn’t need a rendering Que like i do.

    My first thought was i bet the people at Cadsoft are capable of creating the same thing.

    Would it be to late for this update (i don’t know because i don’t know how long it takes to make software changes like that)

    But i would like to hear someone else’s thoughts (from Cadsoft) on this idea (or anyone else).

    Hi
    I posed that to the developers and received the following reply.

    About RTX and the latest hardware. We do support the latest hardware obviously. However, we do not specifically use RTX for now. This is too restrictive in terms of hardware vendors. A scene rendered using RTX on a latest NVIDIA hardware will probably be hard to render identically on other hardwares that have no RTX, so that’s a clear limit in this proprietary technology.

    In layman terms, RTX is only available on a NVIDIA video card. We want to ensure that our users, regardless of the video card manufacturer they chose, can have the best renderings.

    Now the 1000x increase in speed. No. Not even close.

    On NVIDIA’s website they speak of a 10x increase in speed and that is just on raycasting. Our rendering engine already takes the raycasting to the GPU. Renderings take two steps raytrace and radiosity. The increase in speed would therefore be seconds, maybe a minute faster and our raycasting already does that.

    Thanks Chantale,

    I kinda figured there was something i didn’t know.

    Makes perfect sense having something that is available to lot of graphics cards. And not having a limit on it.

    Thanks for for answering the question though appreciate the feedback.

    Real‑time ray tracing, coming in Chief Architect X13, requires a Windows 10 computer with an NVIDIA RTX or an AMD Radeon™ RX 6000 series graphics card.

    https://www.chiefarchitect.com/products/sysreq.html

    Every video card sold is based either on an nVidia chip or an AMD chip…licensed to various video card mfg’s of course. So, what’s this about CA only working on nVidia chipsets?

    Explain it to me ‘in layman terms’ please…
