Optimizing CPU-side Rendering Code

I want to give people a little bit of insight into what the optimization process looks like for Godot’s renderer. From the outside, rendering optimization can look a little bit like black magic. I want to show a few examples of some optimizations that we did this year to highlight that optimizing rendering code isn’t as scary as it sounds. Bottlenecks In this article I will only be looking at optimizing CPU code. When working on renderers, you need to be very careful about optimizing code both for the CPU and for the GPU, because your ultimate performance will be dictated by the slower of the
