Enhancing Unity Game Performance with Universal Render Pipeline (URP)

The Universal Render Pipeline (URP) is a powerful tool that can significantly improve the performance of your Unity game. By leveraging its features and implementing optimisation techniques, you can create a smoother and more responsive gaming experience. In this article, we’ll explore key strategies for performance tuning in Unity games using the URP pipeline. When I started using unity, I had no idea what it was that I was missing, so to help you get started, here are a list of things any Unity developer should know about, and look up.

Utilise GPU Instancing

GPU instancing allows multiple objects with the same material to be rendered in a single draw call. This reduces the overhead associated with making separate draw calls for each object.

void Start()
    Renderer renderer = GetComponent<Renderer>();
    if (renderer != null)
        renderer.material.enableInstancing = true;

Optimise Shaders

URP offers a Shader Graph that allows for visually designing shaders. Keep these tips in mind:

Texture Compression and Atlasing

Optimise textures to reduce memory usage and enhance rendering performance:

Implement Occlusion Culling

Occlusion culling prevents the rendering of objects that are not visible to the camera. This reduces GPU workload.

Level of Detail (LOD)

LOD techniques involve using lower-polygon models or simplified textures for distant objects. URP provides tools for LOD implementation.

Prepare LOD Models

Add LOD Group

Assign LOD Levels

Test and Adjust

Optimise LOD Models

Verify Performance

LOD is effective for objects like terrain, foliage, and complex structures. Apply it to objects with a significant impact on performance.

Particle System Optimisation

Efficiently managing particle systems is crucial for performance:

Minimise Overdraw

Overdraw occurs when multiple transparent objects are rendered on top of each other. This can be mitigated with techniques such as:

Optimise Post-Processing Effects

Post-processing effects can be resource-intensive. Consider:

GPU-Driven Rendering

URP leverages GPU for various rendering tasks. Maximize its potential by utilizing Compute Shaders and other GPU-driven techniques.

Test on Target Hardware

Always test your game on the actual target hardware to ensure optimal performance. This allows you to uncover platform-specific issues and fine-tune accordingly.


Leveraging the Universal Render Pipeline in Unity provides a powerful set of tools for optimising game performance. By utilizing GPU instancing, optimising shaders, managing textures efficiently, and implementing various other techniques, you can create a high-performing game across a range of devices. Remember, continuous testing and iteration are crucial for achieving the best possible performance.
