# ShaderWarmupSetup

> The rendering configuration to use when prewarming shader variants.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine.Experimental.Rendering](/engine/7000.0/script-reference/unityengine/experimental/rendering.md)
* **Assembly:** UnityEngine.CoreModule

> **Warning:**
>
> **Deprecated.** Experimental warmup functionality is deprecated. Please use GraphicsStateCollection instead.

```csharp
public struct ShaderWarmupSetup
```

## Remarks

For information on shader loading and prewarming, including a list of different prewarming techniques, see [Shader loading](/engine/7000.0/manual/materials-and-shaders/shaders/shader-troubleshooting/shader-reduce-stalling/shader-loading.md).

Use this with [ShaderWarmup.WarmupShader](/engine/7000.0/script-reference/unityengine/experimental/rendering/shaderwarmup/warmupshader.md) and [ShaderWarmup.WarmupShaderFromCollection](/engine/7000.0/script-reference/unityengine/experimental/rendering/shaderwarmup/warmupshaderfromcollection.md) to correctly prewarm shader variants for these graphics APIs.
