  • V-Ray Next SSE 4.2 compatible processor issue

    We've been working on V-Ray for the last few years and is one of the most important tools for our work. All the time the V-Ray
    is being upgraded and gets a lot of super new fuctions every time. It's great that it's growing so much and it's getting better.

    My two questions concerns the near future regarding the development of the V-ray and compatibility with existing hardware.
    Our studio has renderfarm in which a large part are computers (node servers) that are already several years old and are not
    the latest models. However, they perfectly meet the expectations of our studio in terms of performance and can cope with
    many difficult tasks. Mainly because there are quite a lot of them. An example specification of such a node is two Xeon
    processors ( mainly X5450, E5450 or L5420 and 64GB ram ).

    The incoming latest version of V-ray Next is to be brilliant and we will certainly want to use it, however, as I have already
    learned the technical requirement is SSE 4.2 compatible processor required. As you can see in my example configuration
    are processors that don't have SSE 4.2. For clarity, I am not suggesting "to stop in time" with the development of the V-Ray
    just to be compatible with old hardware.

    Q1. Are you able to give information whether the New V-Ray Next will not be able to run at all on a computer with
    such a processor or just will certain functions be inactive?

    Q2. We are currently working on V-Ray 3.60.04 for Maya. Is ChaosGroup planning to release another update for Maya
    version 3.xx which will not be a version of Next and will be compatible with this version of processors about which
    I mentioned above and will not require SSE4.2?

    The answer is certainly important for all those who like our studio are still in possession of such hardware.
    Cheers.

    Q1: I don't think so. We use SSE data types all throughout V-Ray now and we use Embree with SSE 4.2 as well. We have a check in the installer that prevents installing on pre-SSE4.2 hardware. Westmere/Nehalem are OK (I'm typing this on a 980XE from 2010), but the older ones will not work

    Q2: There's going to be 3.60.05 at some point with various fixes. It will not require SSE 4.2, so you can safely use it.
