Thanks a lot @vladislavbelov ! The game now runs on my system with Vulkan without any errors for the moment!
(without changing anything from my side, like drivers etc, only game build 27519)
Also, I think that I noticed a small performance boost compared to OPENGL. Hope the performance keep getting better as this is the only thing this game really needs, especially in long games. We hope some day multithreading be a thing. But yeah, Vulkan seems to be superior ! Here are my latest log:
