HSR and TBR

No. Dave could tell you lots about this, cause he's all about tile based rendering. But in short...HSR attempts to remove what is not viewable before it is rendered, often with Z-Buffer tricks(like ATI's HyperZ)....tile based rendering is a totally different way of doing things....it breaks down the screen into small "tiles" that are rendered...it is much more efficient at removing overdraw than HSR.
 
to add to this, HSR is but ONE of many techniques that Tile based rendering uses, for reduction in fillrate and bandwidth requirements.
 
For more info, check out Beyond3d. They regularly have discussions on HSR and deffered rendering. There was a great a thread a while ago with a gentleman by the name SA.

I love linking to this thread. I have it bookmarked.🙂 Check it out.
