I listened well. The process of making the GPU work in Vulkan is really difficult. Buffer & image synchronization... gfx queue, compute queue synchronization... It's fine when drawing triangles, but If I try to make a game engine by myself later, I can imagine that setting up pipeline & renderpass resources will be very difficult. The lecture was great, but Vulkan itself is a bit disappointing 😭 It would have been nice if it was easy for users to make... I look forward to the advanced course~^^
