I'm making a voxel engine with RUST! (the programming language...)
I originally was making my voxel game with Unity, but my love for the Rust programming language caused me to see if it's viable to swap over to that.

This episode is all about optimizing the code for the world generation.
Multithreading, benchmarking, profiling and data compression, are all things I've tackled with lately.
