Not the fastest

This is my 4th Vulkan related "project" and 2nd attempt at making something other than a glorified tutorial workspace in 6 years, and it took me 4 weeks to draw this stuff with minimal technical debt.

I could just use an existing game engine, but what's the fun in not manually sorting all draw commands by mesh>pipeline>material and hunting synchronization hazards by just looking at funny glyphs for extended periods of time?
