In an embodiment, a processor performs one or more operations (such as HiZ or Hierarchical Stencil test) on depth data of an image tile in response to a determination that texture space bounds of the image tile is fully opaque. The processor performs the one or more operations regardless of whether a discard operation is enabled.
