+    Graphical assets used in the UI, such as images, effects, or 3D scenes
+    are a typical cause for performance problems in UIs. Even building the
+    application requires huge amounts of memory if you try to include large
+    asset files, such as 100-MB 3D models or 64-MB textures, into the \c .qrc
+    file for compiling them into the binary.
+
+    First try to optimize your assets, as described in \l{Optimizing Designs}
+    and \l {Creating Optimized 3D Scenes}.
+
+    If you really need large assets, they should either be loaded directly from
+    the file system or use the Qt resource system in the dynamic way. For more
+    information, see \l{The Qt Resource System} in the Qt documentation.
