Enjoy!

Unity Performance: CPU Slicing Secrets - The common wisdom says "profile, optimize, repeat". Let me warn you: this won't always work. Optimizing low-hanging fruits can gain you a whole millisecond in a day. But when those are gone, speeds of 0.1 milliseconds gains per week can become normal. When that happens, you need other tools such as the Unity CPU Slicing technique.

How on-demand rendering can improve mobile performance - It’s not always desirable to render a project at the highest frame rate possible, for a variety of reasons, especially on mobile platforms. Historically, Unity developers have used Application.targetFrameRate or Vsync count to throttle the rendering speed of Unity. This approach impacts not just rendering but the frequency at which every part of Unity runs. The new on-demand rendering API allows you to decouple the rendering frequency from the player loop frequency.

Instancing and Material Property Blocks - By default objects with different materials cannot be instanced together and switching drawcalls is one of the main performance sinks of rendering. Material property blocks (MPBs) allow us a way around that which we can use to change properties on a per object basis.

Making our Unity Analyzers Open-Source - Here at the Visual Studio Tools for Unity team our mission is to improve the productivity of Unity developers. In Visual Studio 2019 we’ve introduced our Unity Analyzers, a collection of Unity specific code diagnostics and code fixes. Today we’re excited to make our Unity Analyzers Open-Source.

Achieve beautiful, scalable, and performant graphics with the Universal Render Pipeline - Universal Render Pipeline is a powerful, ready-to-use solution with a full suite of artist tools for content creation. You should use this rendering pipeline if you want to make a game that has full Unity platform reach with best-in-class visual quality and performance. We covered the benefits of the Universal Render pipeline in this blog post. In this blog post, we’ll dive into how the Universal Render Pipeline was used to create the vertical slice Boat Attack demo.

Temp Memory Reuse - Temp memory is backed by a fixed size block that’s cleared by Unity every frame. Allocations on subsequent frames return pointers to this same block. The allocated memory therefore isn’t unique. How much of a problem is this? Today we’ll do some experiments to find out!

Multi-Scene Loader - Adds a new multi-scene loading system for Edit or Runtime use cases. Unity provides the ability to work with multiple additively loaded scenes at a single time, however there is no 'out of the box' system for handling the loading / unloading of the various scene configurations. This makes working on a multi-user project more complicated than necessary, and most teams end up implementing something similar.
