### Remarks

**Note:** Graphics tiers are only supported in the Built-in Render Pipeline.

Unity generates tier shader variants if your shader source code includes `#pragma hardware_tier_variants`, or if the Tier settings for your project are not all identical.

For more information on Graphics tiers and shader variants, see [Graphics tiers](/engine/6000.3/manual/render-pipelines/built-in-render-pipeline/built-in-graphics-quality-settings/graphics-tiers.md).
