Re: Windows Build FAILED
So where are caches stored, so I can clear/ delete all & make proper comparison? For LuxCore 2.3 it should be: C:\Users\<username>\AppData\Local\Temp\kernel_cache For v2.4 there are two locations: C:\Users\<username>\AppData\Local\Temp\cuda_kernel_cache C:\Users\<username>\AppData\Local\Temp\oc...

Re: Unified executable (for CPU-only, OpenCL and CUDA)
- you can compile the LuxCore sources without having to use OpenCL or CUDA SDK; Do you mean this should work even if compiled with OpenCL "disabled"? There is a problem, though: https://dev.azure.com/LuxCoreRender/LuxCoreRender/_build/results?buildId=2196&view=results These errors hap...

Re: LuxCore API and Unicode UTF-8 support
At the moment, I have done some test only on Linux and it seems to works fine with not-latin languages. I assume MacOS will work too. We need to check Windows. I tried some very simple test on Windows using a filename with non-latin characters: LuxCoreUI opens and renders correctly a file called 'ש...

Re: What is differance?
The difference is that with the first two builds you can choose GPU-based render engines (e.g. PathOCL), having much better performance in many cases. The first build has Cuda enabled: you can use it if you have a suitable Nvidia GPU. Many users reported better performance using the Cuda build with ...

Re: v2.3 Vs v2.4 performance
I find the same very strange behaviour with TAO's scene, i.e. GPU is very slow, with LuxCoreUI 2.2 (but 2.4 is ok).
This line in the config file seems to be the source of the problem, at least on my laptop:
If I comment it, then GPU speed is again very high.

Re: v2.3 Vs v2.4 performance
Repeated tests without PhotonGI and denoiser, same versions as my previous posts, + latest version (with Cache Friendly Samplers): LuxCore2.3 OpenCL: 7906 rays/sec LuxCore2.4alpha0 OpenCL, build 20200430.12: 5325 rays/sec LuxCore2.4alpha0 CUDA, build 20200430.12: 5079 rays/sec LuxCore2.4alpha0 OpenC...

Re: v2.3 Vs v2.4 performance
Here are results with GTX970 (2.3 vs. 2.4 build 20200430.12): LuxCore2.3.jpg LuxCore2.4alpha0_OpenCL.jpg LuxCore2.4alpha0_CUDA.jpg On this card CUDA underperforms OpenCL quite a bit... :? Anyone else with this or similar GPU series can confirm? P.S. With the very latest build, LuxCoreUI exits withou...

Re: PATHGPU with OpenCL and CUDA support
Version 418 seems compatible with 10.1 toolkit, see here:
https://docs.nvidia.com/cuda/cuda-toolk ... index.html
Versions are not shown for MacOS, but I guess major number cannot differ too much.
If you build with toolkit 10.2, you are probably going to need an updated driver.
