Issue #102 - Bigger, Stronger, Faster Performance

All about maximizing performance this week. Well, not all, there is plenty of other topics covered like animation, Unity 2021.2, shader coding, and much more. Enjoy!

Unlit Dynamic Decals/Projection - Often when doing VFX you want stuff to stick to the floor. Even when that floor is uneven. Or decals to make existing geometry more interresting, or you want blob shadows on uneven floor, or some other use-cases in the same direction.

Noise Variants - Combine multiple octaves of noise to create fractal patterns. Introduce turbulence version of Perlin and value noise. Add an option to create tiling noise. This is the fifth tutorial in a series about pseudorandom noise. It adds fractal noise, turbulence, and tiling.

Raymarched Volumetric Lighting in Unity URP - There are a lot of resources on raymarched volumetric lighting on the internet, but in this article, I am going to show you step by step everything you need to know about my own implementation and my modifications over the resources. This includes not just the basic concept, but how to make it performant with good visual quality, using downsampling, randomized sampling, bilateral blur, and near-depth upsampling.

Optimizing performance of Unity games - Optimizing performance of Unity games. Battle tested on 9+ platforms in 13 years of Unity game development. There is an overwhelming amount of optimizations you can make which are impossible to fully cover in this article. Therefore we focus solely on an analysis method you can use, this will inevitably point you to the right optimizations to make for your specific game.

Array iteration performance in C# — Branching and parallelization - Modern CPUs, in a quest for better performance, try to maximize its throughput by executing instructions simultaneously and while waiting for the result of logic tests. They try their best to guess the behavior of our code but, many times, the code has to be adjusted to maximize that potencial.

Cost of exceptions - It’s hard to notice the effect of exceptions if we measure just one exception but they can be fatal to performance when they appear in loops. Let’s dig a little bit deeper.

Start Profiting From Texture Compression in Unity - In this blog post, you’ll learn what texture compression is, why it is important for your project and how to apply it to improve your GPU and memory performance. (And no, we’re not talking about PNG/JPG formats here)

Stream content from a remote catalog with Addressables - Having the ability to load content into a game without forcing the user to download an update is critical to keeping players engaged. There are a lot of different use cases for this. You might want to swap out some models and textures so that they match the holiday season. Or, you can also use this technique to reduce the initial download time of your game by packaging only a couple of levels and assets.

A Simple GPU-based Drawing App in Unity - This week I’m escaping the complicated world of voxels for a bit to do something lighter. We’re building a simple GPU-based drawing app. What does that mean? A drawing app that runs entirely on the GPU using compute shaders. It’ll be just like Photoshop, except without all those complicated features like layers, undo, or a colour picker. Let’s go over the plan.

In this blog post, learn what we’re doing to optimize the core of the Unity Editor so that you can iterate quickly through the entire lifetime of your productions, from importing assets to building and deploying a playable game.

Discover the tools you need with flexible feature sets in Package Manager - To make it easier to accomplish your aims in the Unity Editor, we’ve introduced a concept called “feature sets”. Feature sets contain the packages required to achieve specific outcomes – all guaranteed to work well together, and carefully documented so you can get started quickly.
