Yes but at this point I planning to add also the support for caustic cache with OpenCL before the release of first alpha so it will be nearly feature complete.FarbigeWelt wrote: ↑Mon Feb 18, 2019 7:08 am In my opinion
Current dev. state looks ready for 2.2 alpha1 rool out.
I see. Caustics with openCL sounds good, well actually much better, soundes like musicians are preparing for Harmoy of Standing Waves, 2nd chap. Similarity Dir., Max Pi Well.

It seems somehow the NVidia driver manage to use the RTX or even FMA/AI cores to render. Because from the pure CUDA cores number and frequency, it would make no sens that the 2070 is faster than the 1080Ti. Why they don’t use this automatically in CUDA too is unclear to me though. Maybe to avoid conflict with manually optimized code, but I guess a simple compile directive could solve the problem and bring a great speedup without much work.
Driver can not, it is just not possible. And OpenCL code is always slower than the equivalent CUDA code on NVIDIA GPU ... for obvious reasons, it is not like NVIDIA can even vaguely think to make OpenCL faster than CUDA on their hardware, people would be instantly fired out of the company for such a thingbliblublimathieuMember

It can be easily explain by a larger register file or by mapping local memory as cache, etc. GPUs have still so many bottlenecks when running some huge complex stuff like LuxCore OpenCL code.Because from the pure CUDA cores number and frequency, it would make no sens that the 2070 is faster than the 1080Ti.
