Performance by default

With Unity’s new high-performance, multithreaded Data-Oriented Technology Stack (DOTS), you will be able to take full advantage of multicore processors. DOTS will enable you to create richer user experiences and iterate faster with C# code that’s easier to read and reuse across other projects.

Rebuilding Unity’s core

We’re rebuilding the core of Unity with the Data-Oriented Technology Stack. DOTS makes great games run faster on multicore processors without the heavy programming headache. While most of the Unity packages that are part of DOTS are currently in Preview, some can still make a huge impact in performance-critical areas of your projects today.


Write highly performant C# code

DOTS provides programmers with a convenient sandbox to write safe multithreaded code for massive performance gains, while also optimizing thermal control and battery life on players’ mobile devices. By moving from object-oriented to data-oriented design, it will also be easier for you to reuse your code and for others to understand and work on it.

Create more complex worlds faster

Harness the power of DOTS while using the workflows you already know. 

The new Conversion Workflow converts your GameObjects to entities with one click. At runtime, the new Entity Preview Inspector visualizes how DOTS turns your GameObjects into entities. You’ll get the hyper-optimized, streamable data you need while using GameObjects as you know them today. 

Our new experimental Unity Live Link feature also allows you to iterate instantly in Play Mode without creating a new build every time. You can test the game experience on the target device in real-time and iterate even faster.

DOTS packages

We’re continuously adding new packages to the stack, and you can expect more packages to become verified as production-ready. We highly recommend that you only use preview packages for testing and pre-production phases of your projects.

Sample projects using DOTS

We’ve created several tech demos for you to try that include both source code and assets.

DOTS Sample

Check out the DOTS Sample, an internal test project that combines all current DOTS components, including Unity Physics, Animation, Netcode, and Conversion Workflow.


At Unite Los Angeles, we presented this futuristic cityscape, alive with flying vehicles and a fascinating soundscape, to showcase some of the exciting possibilities with DOTS.

Megacity features 4.5M mesh renderers, 200k unique building objects, 100k unique audio sources, and 5000 dynamic vehicles flying on spline-based traffic lanes.

As part of the Preview release of the Entity Component System, we worked with our friends from Nordeus to create a demo for our Unite Austin 2017 keynote. A cut-down version of the project is available on GitHub.
