Lux Renderer - which version?

I am setting up my new computer and want to try Lux Renderer.

Yeh, I know we now have iray; but Lux Renderer is still around and may even be the best option in Carrara. So my question is which flavor of Lux Renderer would be best tio install. I have a 4Gb nVidia GTX 970 so presumeably I have openCL available and the computer has an i7 processor and 32 GB Ram.

So, would it be better to install the openCL version of Lux Renderer or to install the no openCL version in case I have a scene that requires using the CPU instead of the GPU?

Or will Lux Renderer let me use the 32Gb system RAM with the GTX 970?

    Interesting question since I will be doing the same thing next week when my new rig arrives. I have always used the no OpenCL version in the past (now). When it first came out, the OpenCL was for GPU rendering specifically and in beta, have no idea where it is now and/or viability

    The OpenCL version. The newer versions will use both the CPU and GPU if you tell it to. You only need the Non-CL version if your system throws an error about missing the necessary library for the OpenCL version.

    OpenCL version...basically, if you have any modern video card.  It's not an either/or thing...it's an additional function that is used if needed.

    I've seen at least two recent (as in released in the last two yaers) Intel chipsets that don't support OpenCL. Theyr'e designed specifically for lowend laptops so probably not using them for 3D work, but they do exist. And heck,the system I'm on has a chipset that supports it but can't actually use it. BSODs if you try to use OpenCL at all so you have to use the non-CL version (and thus not use OpenCL at all) to get it to even participate as just a network slave. :)

    Okay...

    But drop a cheap $20 video card (if it's not a laptop) into that system and that should fix it.

    As for Intel...there's lots of things that they do that don't make sense to me, but I suppose being the biggest means they don't have to make sense.

    I'd love to not use the onboard video, believe me :P I don't know what Dell did when designing it, but the thing won't POST past the memory check if you have a PCI video card in it. Other than that it's actually a nice piece of hardware as far as doing the actual rendering goes.I'd say it was a power issue if it didn't have one of these in it: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139140

    Thanks for all your help everybody. I'll just install the openCL version then.

    Thanks again,

    Charlie

    If you will be using Carrara you may be intrested in this beta of a LUXCORE renderer.
