Performance about rust-light-vulkan-engine HOT 1 CLOSED

Yeah that performance does seem pretty poor doesn’t it…

I can maybe think of a few reasons why this might be the case (but idk if this is actually right because I don’t know you gfx/wgpu-Hal code), for such a simple example such as this, every function call would matter. By braking everything up into their own modules there will probably be a bunch of overhead that is really noticeable when we are only drawing one triangle. I would like to see how this code compares to gfx-Hal for more complicated examples though!

But yeah, the purpose of this repository was to translate/port a specific C++ vulkan tutorial as closely as possible, so it could be that this design/layout sacrifices raw performance for better usability. At the end of the day, I am still new to rust and vulkan/ash so have no doubt made a bunch of silly mistakes, but that’s the fun of learning!
