Re: driver level sub-pixel rendering?

[jkheit]

I think some of the cards use the GPUs for scaling video (and perhaps other optimizations). Kind of like the nice upscaling done by some DVD players.  Nvidia calls it PureVideo: http://www.nvidia.com/page/purevideo.html "And the high-precision subpixel processing enables videos to be scaled to any size, so that even small videos look like they were recorded in high-resolution." I'm sure ATI has something similar? I would guess that this kind of thing could also be used for other things sent to it?

It seems a lot of the 3D stuff in the GPU is already employing sub-pixel coordinates, so it would be nice if the actual output to the screen would take advantage of that. AFAIK, nobody's hardware does that. When that kind of antialiasing is done for text, I think it's the job of the font rendering code to do so. -Brian Best regards, John Kheit E-mail: mailto:[EMAIL PROTECTED] AOL Instant Messenger: John Kheit
