Now the reason this works when you load things like windows media player or any other application that needs to run in realtime is the API of the application is taking over the entire system scheduler of your computer and you're using the method it needs. You're basically telling windows "update all my shit now all the time and don't wait." and because of that, your system is working more and harder. If you have a fast cpu, you'll see improvements, if you have a low end to moderate cpu, you may see performance decrease. There's a windows timer function that lets you modify the rate at which the internal clock runs basically xBegin and XEnd API's.īasically you're telling Windows XP don't wait for these timeouts to update our application events - do them as fast as you possibly can. It forces a certain timing scenario to occur with processor instructions and causes a marked improvement in WoW."
