<p></p> <p><b>New page</b></p><div>here&#039;s my 3 sampler stacks.&lt;br&gt;<br /> &lt;br&gt;<br /> http://www.kjams.com/resources/code/picture1.png&lt;br&gt;<br /> &lt;br&gt;<br /> in this first one, i call CGraphics::Update(), this is where I actually create the CGImage, which takes only 1 sample (from 273 to 272) so i don&#039;t show it. then i loop over the destinations, telling each port to suck in the image, and you can see where most of the time is going.&lt;br&gt;<br /> &lt;br&gt;<br /> http://www.kjams.com/resources/code/picture2.png&lt;br&gt;<br /> &lt;br&gt;<br /> the rest of the time is going to erase the background first, shown above&lt;br&gt;<br /> &lt;br&gt;<br /> http://www.kjams.com/resources/code/picture3.png&lt;br&gt;<br /> &lt;br&gt;<br /> and after i erase and then blit, i also do an overlay of text using a transparency layer, but that only happens for a few seconds so i&#039;m not very worried about that speed hit.<br /> <br /> Below, here&#039;s what QuartzDebug has to say. the hilited row is my video window. do i need to make it a compositing window or something?<br /> <br /> http://www.kjams.com/resources/code/picture4.png&lt;br&gt;</div>
