OpenCL Vs Software ? On Win 10
-
It seems that I am a bit undereducated
I hope someone can explain to me the difference between
"Software" and "CL (OpenCL)" in the Preferences > Performance panel.Why or when it might be better/meaningful to select one or the other.
My specs are:
Win 10
CPU: AMD Ryzen 5 5600X, 6-core.
GPU: Nvidia Geforce RTX 3070.Thanks a lot in advance.

@Subpath The Compute Engine option controls how image effects, gradient meshes, etc are rendered.
If you have NVIDIA GPU, the following options should be available (with explanation):- Software: all image effects, gradients, noise etc are computed using all the CPU cores. In your case 6 cores, with hyperthreading could be 12 threads (this can be changed in preferences).
- OpenCL: image effects, gradients etc are computed using the GPU, with OpenCL compute. This should be available for most Windows machines with a GPU, but how well it works depends on the OpenCL driver.
- NVIDIA: this should be available if NVIDIA CUDA drivers are installed. With NVIDIA GPU this is the best choice, in this case image effects, gradients etc, are computed using CUDA compute.

@vectoradmin ,
Thank you for your, as always, clear and well described
explanation of how "CL" and "software" works.
