Windows Build FAILED
Re: Windows Build FAILED
Yes, it is the same with the cuda version and also the opencl only version.

Re: Windows Build FAILED
Just updated Blendluxcore with the content of LuxCore commit 071e1cb (tentative fix for an OpenCL crash), but still get a crash when trying to render the Benchmark scene with GPU devices selected as OpenCL (Cuda works).
Re: Windows Build FAILED
I have installed cuda sdk 10.2 for the new compilation of the new code. The old one I had installed was 8.0, IIRC. Could that be the source of the problem of the error messages?

1. OCL renders only final, but image intensity goes darker as rendering progresses/ viewport goes instantly black
2. OCL+CUDA together, show mixed result // Viewport is striped, tiled had this happening before selections were added
3. CUDA fine
4. CPU fine
BTW
UI wise, I think there should just simply be CUDA Device option added in dropdown menu, which would automatically deselect NVidia's OCL to prevent the confusion and extra settings
Re: Windows Build FAILED
The UI will be improved of course.
Re: Windows Build FAILED
Indeed, I have faith in you... was just stating the obvious
I really find this engine becoming the first true hybrid in nature (all vendors) simply amazing.
But alongside (offtopic), I'm quite puzzled about how you'll define "Devices" while still offering a choice between OCL/CUDA for NVidia in a mixed system.
Respect
BTW
Should this topic be split as it already builds fine on Windows, and we've started to bug fix the version in development?

Re: Windows Build FAILED
Hi, I test only small scenes but does anybody have the same performance boost like me?
It is about 1.8 times faster than OCL on my stone age GTX 760.
Thank you for implementing it @developers.

There seem to be a pattern: small GPUs gain a LOT from CUDAmib2berlin wrote: ↑Tue Apr 28, 2020 9:28 pm Hi, I test only small scenes but does anybody have the same performance boost like me?

I have a similar boost result on my old (gtx960 4gb)mib2berlin wrote: ↑Tue Apr 28, 2020 9:28 pm Hi, I test only small scenes but does anybody have the same performance boost like me?

Tell me, is cuda also now involved in the viewport rendering? It also feels like a faster viewport (no delays,lags, faster compiling)
Actualy sorry for my google translate english :)

With cuda my GTX 780 is 1.5 times faster than the GTX 1080. Is it normal behaviour?
It seems we have a wide variety of results, mostly improvements but not all of them.
Also a GTX780 faster than a 1080 is quite strange, isn't it? The 1080 has more Cuda cores and nearly double clock speed and memory bandwitdh than the 780.
