 Textures that have been loaded from a file, as well as vertex & index buffers that have shadowing enabled will restore their contents automatically, the rest have to be restored manually. On Direct3D9 non-dynamic (managed) textures and buffers will never be lost, as the runtime automatically backs them up to system memory.
 
-See \ref GPUObject::IsDataLost "IsDataLost()" function in VertexBuffer, IndexBuffer, Texture2D and TextureCube classes for detecting data loss. Inbuilt classes such as Model, BillboardSet and Font already handle data loss for their internal GPU resources, so checking for it is only necessary for custom buffers and textures. Watch out especially for trying to render with an index buffer that has uninitialized data after a loss, as this can cause a crash inside the GPU driver due to referencing non-existent (garbage) vertices.
