Why Unity 2021 LTS

Faster iteration to get to quality

Achieve quality faster through improved workflows, better Editor usability, and enhanced testing tools. Spend your time in the Editor more efficiently with improved search and a host of speedups across common operations. Create clean, performant code with improved C# 8 support. Test better with the mobile Device Simulator and Code Coverage package with Test Runner.

More accessible creative workflows

With the Unity Editor, you can now build immersive experiences faster than ever. Do more with less code using an integrated visual scripting solution and improvements to the VFX Graph, Shader Graph, and Cinemachine. Worldbuild faster with upgrades to Terrain tools, and leverage our most powerful 2D toolset yet.

Powerful scriptable render pipelines

Create platform-optimized graphics with the Universal Render Pipeline (URP), or focus on fidelity with High Definition Render Pipeline (HDRP). URP upgrades such as decals, Point Light shadows, and Lens Flare bring it closer in parity to the Built-In Render Pipeline. Push the limits of high fidelity with HDRP performance upgrades and features like NVIDIA DLSS for desktop, Volumetric Clouds, and Static Shadow Caster.

Reach new generations of players

Be where your players are with support for new platforms and technologies. Expand your development capabilities with ChromeOS and macOS-based Apple silicon support, and achieve even more impressive results on PlayStation 5 and Xbox Series X|S consoles. Develop for a new ’verse with OpenXR and Oculus enhancements, or create for mobile with Samsung Adaptive Performance 3.0 for optimizations and Android asset bundling for seamless publishing.
