Check the number of native threads you have in OpenCL, it must be > zero. It renders fine here.

CPU threads are set to auto-detect, which come up as 8 for me.

I tested it here (win10, Bl2.81, Lux 2.4 daily from ~3 days ago) and it works fine. I downloaded you scene, rendered directly (CPU), switched to OpenCL setting, rendered again.

OCL:

That would be because I use the ACES tonemapping

Did a fresh install of latest Blendluxcore, same problem.

How about the OpenCL/GPU drivers? This wasn't mentioned in this thread yet, and dirver problems have occured in the past.

What are you system specs actually?

Ryzen 5 2400g
Radeon Rx570
Radeon Software 20.2.1

I'll update and test again tomorrow

Try to check also your CPU load during the rendering

Tested and confirmed - working fine w/o any visual difference in CPU vs OCL rendered images (even when using ACES color management).

Updated to 20.4.1, still not correct. CPU load reaches 100% in task manager. This must be hardware specific if other people cannot reproduce it.
