Probably you wrote with a smile on face, but as I can't see you, I can't understand the reason why supporting CUDA/Optix exclude "small and quality of life features"?

Because supporting CUDA needs to rewrite everything and so, before add feature you prefer to make this "switch" or because your development time will be full drained by this CUDA/Optix support?

Which benefit will have us with this? (and consider I'm with Nvidia in any PC I use)

Yes, it is not a small undertaking, it will cost a lot of time so, given the limited amount of time/resources, it would delay the development of other stuff.

An hypothetical LuxCore "PATHRTX" render engine is likely to run quite faster than current LuxCore "PATHOCL" render engine on NVIDIA RTX GPUs (the one with hardware acceleration). It may also run a bit faster on older NVIDIA GPUs supported by OptiX (because their code is likely to be faster than our generic OpenCL code even without RTX hardware).

But AMD users will still be able to LuxCore with this switch?

Or it's just "another" option: CPU, OPENCL and CUDA/OPTIX ?

Yes, it will be another option only available if you have a RTX capable GPU.

Someone needs to call nvidia and tell them the news...

Luxcore is gonna become the next RTX benchmarking tool of choice :D

For me by priority :

1__ Reduced average time before rendering start ( caches, opencl compilation, scene data loading )

2__ Micro Displacement (adaptive subdivision / Vector displacement )

3__ Hybrid Glass

4__ support for 3D LUT (.cube)

but OpenCL is a dead dinosaur
As opencl is an open standar what is going to be set as a replacement worldwide not only for luxcore ?

I've forgotten another high priority for Blender addon: preview textures on viewport

The only hope is to have Intel come out with a really good GPU (very unlikely, given their endless number of past failures) and, at that point, they will need to expose their hardware trough some computing standard to fight CUDA. But it probably easier to win at lottery...
