| --------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Hardware acceleration**   | <p>Select in the drop-down list how Remote Desktop Manager will handle hardware acceleration:</p><ul><li><em><strong>Default (Automatic)</strong></em>: Graphics rendering is completely left to the operating system.</li><li><em><strong>Disabled (GDI+)</strong></em>: Hardware acceleration is forced disabled.</li><li><p><em><strong>DirectX</strong></em>: Hardware acceleration is forced enabled. The graphics rendering is performed by the graphics card. Performance is sped up in some cases, which is often required for high resolutions.</p><p>This setting does not need to be modified unless there are UI performance issues.</p></li></ul> |
| **Optimize UI Performance** | Optimize the user interface for better performances.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           |
| **Session list refresh**    | Set the refresh delay for the opened connection tree.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          |

#### Avalonia rendering <a href="#avalonia-rendering" id="avalonia-rendering"></a>

| OPTION                                          | DESCRIPTION                                                                                                                                                       |
| ----------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Enable AngleEgl rendering mode**              | Use ANGLE (Almost Native Graphics Layer Engine) with EGL to translate OpenGL ES API calls into hardware-supported APIs like Vulkan, Desktop GL, or Direct3D 9/11. |
| **Enable direct composition mode**              | Use Windows DirectComposition for faster, hardware-accelerated UI rendering.                                                                                      |
| **Enable redirection surface composition mode** | Render offscreen first to prevent tearing and glitches.                                                                                                           |
| **Enable software rendering mode**              | Force UI rendering using the CPU instead of the GPU.                                                                                                              |
| **Enable WinUI composition mode**               | Leverage modern Windows UI features for smoother transitions and animations.                                                                                      |

#### Other options <a href="#other-options" id="other-options"></a>

| OPTION                 | DESCRIPTION                                                                                                                                                               |
| ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Show custom images** | Enable the loading of custom images in the tree view. Note that too many custom images could dramatically increase the size of the workspace and load time.               |
| **Show favicon cache** | Enable the favicon cache to store favicons locally, avoiding fetching them from the web on every load. Disabling this feature is not recommended for performance reasons. |
| **Enable gravatars**   | Enable Gravatar images to display profile pictures associated with user accounts throughout the application.                                                              |
| **Show user gravatar** | Display the Gravatar profile image associated with the current user.                                                                                                      |
