Windows 7 Misreading CPU Usage?

    Right now, here's what I'm doing on my laptop:


    • typing this up
    • burning a DVD9 disc
    • extracting an 8gb rar file
    • chatting on AIM
    • running Outlook 07
    • Watching Conan on Hulu.com
    And the Task Manager claims my CPU is only at 11%. Now, it doesn't feel slow, but such low CPU usage is extremely unusual!

    Here are my specs:

    Windows 7 x64 Build 7000
    T7300 CPU @ 2GHz
    4GB RAM DDR-677
    8600M GT 256MB GDDR3 RAM 550/900 clocks

    Am I right in my assumption?

    About the only thing cpu intensive in that list is winrar extracting the 8gb file. And even that is partly hard disk intensive, much like burning a dvd. Everything else isn't cpu intensive so 11% on a dual core machine sounds about right.

    Well I'm telling you: This would've been a 100% CPU usage session in Vista x64. I know cuz its not the first time I do something like this. Flash video is normally a CPU hog, ask anyone.

    Well I believe you if you say so, though logically I don't get why Flash video would use 100% of your cpu. I'll have to google it and see. But thus far, doing some video encoding (720p h.264), cpu usage has been about the same in Win 7 as Vista x64. Roughly 80% cpu usage on all 4 cores on the 1st pass and 100% cpu usage on all 4 cores on the 2nd pass.

    No, flash video takes between 28 and 48% CPU usage on its own normally on this machine. It might be something with IE8 as I see that still in Firefox it takes a lot of CPU. Watching h.264 or any other normal codec on my machine has always taken less resources than 480p flash video.

    As far as video performance, under Windows 7 x64, my computer runs 1080p video smoothly. Under Vista x64 it was a little laggy.
