The write-up itself is long and rather technical, but the main section of interest to gamers deals with unnecessary CPU resource consumption. Apparently, Vista does a sweep of all computer hardware over 30 times every second to make sure no one is trying to leech a digital video signal through a modification. Besides taking up valuable computing cycles, this method also makes it harder for the computer to perform video decompression, especially in low-end graphics chips.
While it remains to be seen how these "features" will actually impact Vista games, the fact that it's even an issue is enough to make us question Microsoft's devotion to Vista gaming. As the analysis' author puts it, "I wonder how [the gaming] market segment will react to knowing that their top-of-the-line hardware is being hamstrung by all of the content-protection "features" that Vista hogties it with?"
