# Frame Settings reference
Frame Settings all include the following properties.
### Rendering
These settings determine the method that the Cameras and Reflection Probes using these Frame Settings use for their rendering passes. You can control properties such as the rendering method, whether to use MSAA, or even whether the Camera renders opaque Materials at all. Disabling these settings doesn't save on memory, but can improve performance.

<tbody>
<tr>
<td><strong>Lit Shader Mode</strong></td>
<td></td>
<td>Select the Shader Mode HDRP uses for the Lit Shader when the rendering component using these Frame Settings renders the Scene.</td>
</tr>
<tr>
<td></td>
<td><strong>Depth Prepass within Deferred</strong></td>
<td>If you enable Decals then HDRP forces a depth prepass and you can not disable this feature. This feature fills the depth buffer with all Meshes, without rendering any color. It's an optimization option that depends on the Unity Project you are creating, meaning that you should measure the performance before and after you enable this feature to make sure it benefits your Project. This is only available if you set <strong>Lit Shader Mode</strong> to <strong>Deferred</strong>.</td>
</tr>
<tr>
<td></td>
<td><strong>Clear GBuffers</strong></td>
<td>Enable the checkbox to make HDRP clear GBuffers for Cameras using these Frame Settings. This is only available if you set Lit <strong>Shader Mode</strong> to <strong>Deferred</strong>.</td>
</tr>
<tr>
<td></td>
<td><strong>MSAA</strong></td>
<td>Select the MSAA quality for the rendering components using these Frame Settings. This is only available if you set <strong>Lit Shader Mode</strong> to <strong>Forward<strong>.<br/> <strong>Note</strong>: Using a different value for multiple different cameras has an impact on memory consumption.</td>
</tr>
<tr>
<td></td>
<td><strong>Alpha To Mask</strong></td>
<td>Enable the checkbox to make HDRP render with Alpha to Mask Materials that have enabled it. This is only available if you enable <strong>MSAA</strong> within <strong>Forward</strong>.</td>
</tr>
<tr>
<td><strong>Opaque Objects</strong></td>

### Light Loop Debug
Use these settings to enable or disable settings relating to lighting in HDRP.
**Note**: These settings are for debugging purposes only. Each property here describes an optimization so disabling any of them has a negative impact on performance. You should only disable an optimization to isolate issues for debugging.
| **Property** | **Description** |
| ----------------------------- | ------------------------------------------------------------ |
| **FPTL For Forward Opaque** | Enable the checkbox to make HDRP use Fine Pruned Tiled Lighting for Forward rendered opaque GameObjects. |
| **Big Tile Prepass** | Enable the checkbox to make HDRP use an optimization using a prepass with bigger tiles for tile lighting computation. |
| **Deferred Tile** | Enable the checkbox to make HDRP use tiles to calculate deferred lighting. Disable this checkbox to use a full-screen brute force pixel Shader instead. |
| **Compute Light Evaluation** | Enable the checkbox to make HDRP compute lighting using a compute Shader and tile classification. Otherwise HDRP uses a generic pixel Shader. |
| **Compute Light Variants** | Enable the checkbox to classify tiles by light type combinations. Enable Compute Light Evaluation to access this property. |
| **Compute Material Variants** | Enable the checkbox to classify tiles by Material variant combinations. Enable Compute Light Evaluation to access this property. |
