Performance

More horsepower to seamlessly create and deliver world-class game experiences

Unity 2020 LTS

The LTS release is for creators who value maximum stability and support. It includes improvements to streamline your coding experience, improved testing and profiling, and other enhancements. Achieve more in less time, all with a smoother workflow – then deliver your game to the widest possible audience.

First seen in 2020.2, Safe Mode is now in the 2020 LTS

Quality

Unity now comes with Safe Mode, so you can load up the Editor with a simpler interface to address any compilation issues in your project. This lets you focus on providing a great experience for your users by harnessing streamlined productivity and a superior development experience.

Productivity

Unity 2020 LTS improves coding efficiency by supporting most of the latest C# 8 syntax additions such as streamlined switch expressions and nullable reference types. Unity supports many other additions to C# 8 to give you the ability to write less code for more functionality.

Performance

Developers, get the most out of your project with our profiling tools. In the Unity Profiler, you can now see performance data in charts, gain insights into serialized functionality to identify potential areas ideal for multi-threaded code, and a Profiler API that exposes performance data points at runtime.

Build once, deliver anywhere

Take your content anywhere your users want you to be. With Unity, you’ll get the most out of today’s hardware, including AR, VR, mobile, and PC devices – and be ready for whatever comes next.

OpenXR support

Unity now supports OpenXR, an open standard provided by Khronos, to help you maximize your reach across a wide range of AR and VR devices.

AR Foundation 4.0

AR Foundation 4.0 supports ARKit scene mesh reconstruction using LiDAR sensors on the iPhone 12 Pro and iPad Pro to enable AR experiences that bring a new level of realism.

Quest 2 support

Leverage Unity’s latest features and technology to bring stunning experiences to life on the Oculus platform. You can also use Oculus Link to iterate on projects directly from the Unity Editor.

Adaptive Performance 2.0

Adaptive Performance 2.0 comes with sample projects to showcase new features including Variable Refresh Rate, Scalers, and the Adaptive Performance Simulator extension, which emulates Adaptive Performance on any device.

Quality

The Scriptable Render Pipeline (including Universal Render Pipeline and High Definition Render Pipeline) is now part of the Unity core. This simplifies the experience of working with new graphics features and ensures that your projects are always running on the latest verified graphics code.

Productivity

We’ve made improvements across the board to give you faster build times. From general C# script compilation improvements, including background compilation of some scripts, to IL2CPP and UnityLinker enhancements, you’ll notice a much speedier experience in going from in-Editor to Play mode and back again.

First highlighted in 2020.2, visualize render and memory Profiler stats in Players along with other productivity enhancements.

Performance

2D Sprite Processing improvements are faster, with lower memory usage when processing large numbers of sprites, with new process options and faster sprite slicing. Sprite Libraries assets enable you to easily swap out sprites to customize environments or characters. 2D Tilemaps also received UX and stability improvements.

Frequently asked questions

What version do you recommend for my project?

If you are in production or close to launch, we recommend the latest LTS release. If you want to use the latest Unity features in your project or are just getting started with production, the Tech Stream is recommended. Learn more about our different releases here.

What is a Tech Stream release?

This release is for creators who value exploring in-progress features to stay on the cutting edge for their next project. This version is primarily recommended for the preproduction discovery, and prototyping phases of development. Learn more about our different releases here.

What’s an LTS release?

The release for creators who value maximum stability and support for their next project. This is our default release and is primarily recommended for creators past the preproduction phase of development and who are about to lock in production on a specific version of Unity. 

Learn more about our different releases here.

What’s the difference between a Verified package and a Released package?

In an effort to provide more clarity around package readiness and expected release date, better quality packages, and as a direct response to feedback from you, we’ve created a more rigorous process for labeling packages, as well as a new categorization system. Learn more here.

How do I get access to your alpha and beta releases?

Both our alpha and beta releases are open to everyone, so no signup is required. Get started by downloading them from the Unity Hub. Because there may be feature-stability issues with these early releases, we do not recommend them for projects in production, and we highly recommend that you back up any project before you open it with an alpha or beta release.
