Show HN: Flo Is a Rust/Vulkan 3D Renderer for the Bevy Game Engine

2 points by wkwan 16 hours ago

I’m using the excellent Bevy game engine for my colony sim/action game, but I do lots of real-time procedural generation/animation so the wgpu renderer is too slow.

So I wrote my own Rust/Vulkan renderer and integrated it with Bevy. It’s ugly, buggy, and hard to use but multiple times faster.

Full source code, with 9 benchmarks comparing performance with the default wgpu renderer: https://github.com/wkwan/flo

Video where I go over the examples and run them on the Steam Deck: https://www.youtube.com/watch?v=y1m30oOksmI
