Hello Jan,

I'm so blind...
...bumping it 48 and 64 (first try) works. 33 not ;-)
We shouldn't waste to much memory.
Now, let's start with the libclc work.
Luxmark 'Hotel' is very blocky and Blender 'barbershop_interior_gpu' 
mostly black. I have some images.

Shouldn't we better open a new ticket. Any hints for a good name?
Or do we have one already? I can put my pictures, there.
Simpler scenes work, but mostly gray (without colors/texture).
