sure thing , i checked the NVIDIA Inspector, it can save only csv file , is this a helpful format for you ?

or do you need an image chart ?

Anything should be okay.
The GPU usage in task manager show different usage than the GPU tweak on my pc

yeah , that's why i don't rely on the Task Manager charts as the are always not correct, that's why i use NVIDIA Inspector.

I will try also to check MSI Afterburner too

1 GPU: 2 GPUs:

I don't know if modifying a post will send a notification to people , so i will write this empty post to notify you TAO

As i noticed , you are looking in the GPU Tweak at the "GPU Clock", this is not what you are supposed to look at , look for something like "GPU Usage".
your GPU clock could be at full Clock Hz, but your GPU usage is 0 .

I can confirm TILEPATHOCL is slower than PATHOCL and it just uses less than 20% of GPU.
I will investigate to see if the issue has come from MaxToLux or LuxCore itself.

It is normal if the tiles are small and/or the AA is low: the tile (with AA) is the basic task of TILEPATH, if the work is small, the overhead of CPU<=>GPU communication can become larger than the work itself (so the GPU load is very low). Just use an higher AA and you will see the GPU load to increase.

In general, there is no reason to use tile rendering in LuxCore for anything but very high resolution images (i.e. 8+K) where the saved GPU memory can become important.

Very useful information.
Thank you.
