Does vulkan only run on some gpus?

Do you have a compatible Vulkan installable client driver (ICD) installed?
Please look at the Getting Started guide for additional information.

MY gpu is NVS 5200M, I couldn't find it in any of these two websites https://developer.nvidia.com/vulkan-driver https://vulkan.gpuinfo.org/ Is this what is causing the error? I can't use vulkan on this gpu?

Would you mind sharing how you solved that issue? The error message indicates that you are missing the vulkan driver of your dedicated gpu. For primus_vk to work, you need a vulkan driver for each, the integrated and the dedicated gpu, to both work.

@felixdoerre Turns out my gpu doesn't support vulkan, so I can't use it.
