<i>The fact that it takes up to 80 percent of the CPU in a quad-core 2.66GHz Mac Pro to render a 400x300 Flash game just boggles my mind</i><p>The reason is because Adobe developers don't use hardware 3d graphics acceleration.  They do everything in the processor because they don't know how to write code that works on multiple types of hardware or maybe they are too lazy or cheap, I don't know.<p>The effect is that <i>ALL</i> of their apps run dreadfully slow on all platforms because every single calculation has to go through the CPU.<p>This is just one of the many reasons Adobe software is some of the worst on the market.
