Passei muito tempo pesquisando o motivo pelo qual o Vulkan não funciona no meu sistema.

Eu tenho a NVIDIA GT 520 com o driver mais recente instalado, mas muitas horas depois parece que a minha GPU está apenas na lista de tecnologias suportadas link
Espero que o Ubuntu, pelo menos, me avise que não há suporte para minha GPU. Por que isso não acontece? É possível fazer essa verificação em nível de sistema ou pelo menos fornecer listas de cartões com explicações?
