How to enable super resolution?

[tormento]

Apart from unzipping the model file, have I to do something else?

I see it grayed out when right clicking on image.

Unzipping a model alone is not enough. The context-menu item is enabled only when an image is loaded and the Super Resolution plugin is installed and enabled.

The easiest route is:

1. Open Settings → Plugins.
2. In the marketplace, install the Super-Resolution AI / Real-ESRGAN NCNN Vulkan component.
3. Return to Installed Plugins, select the model, download it if necessary, and turn on the Super-Resolution AI toggle.
4. Restart QuickView, open a raster image, and try the context-menu item again (the default shortcut is Shift+S).

If installing manually, keep the component and both files for the chosen model in the layout expected by the plugin:

QuickView.exe
plugins/sr/sr_ncnn_vulkan/sr_ncnn_vulkan.qvx
plugins/sr/sr_ncnn_vulkan/models/<model>.param
plugins/sr/sr_ncnn_vulkan/models/<model>.bin

So check that you extracted both the .param and .bin, not only the model archive, and that the .qvx component itself is present. The current code explicitly greys out the menu when GetSrPluginInstallState() is NotInstalled or IsSrPluginEnabled() is false: ContextMenu.cpp.
