I wondered if there are any special things you can do within Windows XP to optimize it for gaming. You can see my specs' in my signature. I found that after upgrading to XP that games didn't run as smoothly or efficiently as previous Windows versions, I've fixed the refresh rate lock problem, but it's still just not so good. Can anyone give me a list of Services that are safe to close, to free up system resources. Any ideas will be helpful thanks, Ps is there a fix for Enter The Matrix not working, after a refresh rate fixer has been used? After using reforce this comes up while trying to start the game "Error Creating Device 2", this is fixed be undoing the reforce changes, but this is not conveniant for games where I need the reforce changes on, to get full fps and performance.
