### Remarks

When a collection is "warmed up", all the GPU representations of the shader variants and graphics states in the collection will have been created. This is the case when [GraphicsStateCollection.completedWarmupCount](/engine/6000.5/script-reference/unityengine/rendering/graphicsstatecollection/completedwarmupcount.md) is equal to [GraphicsStateCollection.totalGraphicsStateCount](/engine/6000.5/script-reference/unityengine/rendering/graphicsstatecollection/totalgraphicsstatecount.md).
