If i turn off 4 lights sources of 5, the artifact still shows up. At the beginning i was thinking about caustics caused by the chrome material, which is the only shiny one of the scene, but no, even if i turn off the chrome the artifact still shows up.

Yes, probably we are writing something in the wrong way but we cannot figure out what.

Hi to all, we are integrating Luxcore in to www.felixrender.com with the purpose to offer a bidirectional rendering tool for architects at reasonable rendering speed. We have a problem with the attached scene. Rendering on luxcore 2.4 is much slower as on Luxcore 2.2 and a wired artifact is showing ...

Hi Dade, fine. We have to setup for you a special machine because we cannot give the access of the machines we are currently using. Probably within 10 days we can give you full access to one or two xeon 2698 V4 with 80 cores. In the meanwhile thanks!

Hi, we did extensive tests on AWS. Same behaviour. Till 28 cores everything fine. Rendering with 96 cores is three times slower as the 28 cores machine. Do you need precise details? Can we help?

Dade solved our problem i think. In our test we have been using a scene which uses the old denoiser which is slow and almost single core. This caused a bottleneck on dual xeons with many cores. The intel denoiser is super fast and apparently allows to scale up more linearly. Monday we complete our t...

following are the render settings i used: # For a description of the CFG properties, visit: # https://wiki.luxcorerender.org/LuxCore_SDL_Reference_Manual_v2.1 # Do not use OpenCL CPU devices (native C++ rendering is faster) opencl.cpu.use = 0 # Use all GPU devices we can find opencl.gpu.use = 1 # Yo...

thanks FarbigeWelt, i normally use the Spec 2017 fpRates which are quiet precise too.
Wen rendering with luxcore the 2697 uses 100% of the cpus almost all the time. that's why i'm a bit lost. Should be at least 30% faster.

because i already have the hardware. I just want to use it with Luxrender and i want to understand Luxrender's behaviour. Thanks!

Hi to all, this is my first post here. I have a question regarding LuxCorerender performance on xeon dual processor servers. The test escene is LuxCore 2.1 Benchmark downloaded from the download area. OS is debian 64 buster Render engine type Pathcpu Sampler Sobol Dual Xeon 5520 ,3 ghz (8 cores)= 74...
