Hey Murph, Glad you made it to XP, and I know you'll be glad even if there are any bumps at first. If so, somebody will be here to help. I've been running reasonably smooth for a while now. Now, my friends Mike(Quikdraw) and DaBasstard helped me (as usual) when I went to XP Pro, and as soon as I got it installed, Mike gave me the basic 'follow up' advice below. So just in case, here it is for you too. I also saw in a recent thread where Quikdraw had tested all the so-called extra 'tweaks' he could find, and he found that really, none of them improve performance of PT. So according to that, PT should work fine with XP as it is. BUT, don't forget to: Set a recording limit in PTLE Set CPU usage to 85% Set PTLE to allow background recording applications To set Windows processor usage to Background Services. Right-click My Computer, choose Properties, click the Advanced tab, click the Advanced button under Performance. Select Background Services. ~Roy
