Are you running Cycles in OpenCL or CUDA mode ? I assume you have used the CUDA version. Can you try to run the OpenCL version so to play a more fair match ?
Faster that octane? Are you sure? Does octane even run on opencl?Dade wrote: Tue Oct 23, 2018 3:48 pmAre you running Cycles in OpenCL or CUDA mode ? I assume you have used the CUDA version. Can you try to run the OpenCL version so to play a more fair match ?
Side note: CUDA is faster than OpenCL on NVIDIA hardware (even when using exactly the some code). This is somewhat a political choose, for obvious commercial reason. Just to say that if you spend the same money of 2xGTX on 2xAMD GPUs, I have the feeling LuxCore will come out faster than Cycles and Octane.
Octane doesn't run on OpenCL and it is the reason why I suggested to fix a budget and than compare LuxCore+AMD GPU+OpenCL Vs. Octane+NVIDIA GPU+CUDA. I would be quite curious to see the end result.lacilaci wrote: Tue Oct 23, 2018 5:15 pm Faster that octane? Are you sure? Does octane even run on opencl?
hmm software cost... Octane 4 when released should be free for 2 gpus(unless something changed, this was advertised). Cycles is free and open source... And I guess if you need more then renderfarm could be a good option, I did use cycles on rebusfarm and would probably use luxcore on renderfarm too for commercial projects at some point.Dade wrote: Tue Oct 23, 2018 6:38 pmOctane doesn't run on OpenCL and it is the reason why I suggested to fix a budget and than compare LuxCore+AMD GPU+OpenCL Vs.

I could also suggest to factor the software cost when doing this test too![]()
P.S. you could also throw in some consideration about power consumption but, sincerely, it is start to be important only for some large scale installation and not for private/small studio uses.

Or you can wait for official release of Octane 4 that should be free to use for 2 gpus.Dade wrote: Tue Oct 23, 2018 10:51 pmOtoy writes, on their sites, that is $399 for a single license standalone version: https://home.otoy.com/render/octane-render/purchase/lacilaci wrote: Tue Oct 23, 2018 7:03 pm hmm software cost...

Octane+Blender plugin is $599.
You can render with one additional (quite fast) GPU for the same budget if you use LuxCoreRender or Cycles. Not exactly a small difference.
So what do you suggest to do ?Or you can wait for official release of Octane 4 that should be free to use for 2 gpus.
Of course today it's not free, but today Luxcore is in alpha stage with many features missing and important features like denoiser and dlcs are slow and unreliable.
