Unable to use discrete NVIDIA card on Linux. - Mutual GNU / Linux

Hi,

as many users, I have a discrete NVIDIA card, to use it for any software I have to pass proper environment variables, which I do so. In Steam it is:
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia __VK_LAYER_NV_optimus=NVIDIA_only %command%

Works in any game but not Ryzom, I also tried to unlink from Steam and use a simple bash script to pass these options to Ryzom launcher (also works in any game)

But it crashes badly, so I guess something is wrong on your side.

Please let me use my NVIDIA card because dual-GPU laptops usually have a rubbish Intel card and a nice discrete one.

See the listings below, core file available upon request:
