In theory this may even work but: every pending RenderSession will keep a full copy of the scene in ram. You can just keep resizing the view port and the memory usage will increase and increase
Can this have an impact on viewport responssivness ?

You can very easily run out of (CPU) memory and start to swap (i.e. bigger is the scene and less copies you will need to run out of memory).

Updated to the last build aviable 2hrs ago...And no more Errors.
Just regular crash from the viewport when switching from preview to solid.

The NVIDIA Q600 is a Fermi GPU, it is very old: I think it was released about 10 years ago. The driver doesn't support a CUDA version recent enough to be able to run LuxCoreRender.

I'm afraid you can run only CPU rendering and you can not use the GPU.
