<div>The traditional overlay would handle YUV to RGB conversion, scaling, color control, and keying. I don't have in depth knowledge of the nVidia architecture. However I would expect most of this is now accomplished using programmable 3D functionality. The trend is to now render in source resolutions and then scale just before output. Microsoft has much to do with arrangement.

<div>Newer cores will have less fixed function overlay support, relying on compositing with the 3D engine instead.</div><br> </div>
