    CPU utilisation very high in IE10


    I have to use Firefox 6 for the time being as IE10 utilises high CPU(60%-70%) and causes my temperature to rise. Has anyone noticed or had this issue?

    I have found the immersive apps (or Metro Apps) often have high CPU usage.

    In my case, particularly, it's the Weather app when I have it placed on the side:

    It's for the regular desktop IE, FF takes up about 12% and the temps are normal for the usual tasks, when I browse with IE even idling temps are in the 50s.Click image for larger version

    I found Windows 8 DPC latency very high in-comparison to Windows 7 on the same machine, With this latency I'm surprised people can play games etc... I guess most machines are absorbing the extra work without much noticeable difference.

    (DPC is basically the kernel-mode driver work queue, higher latency = slower software execution)

    This morning the CPU usage has gone down to normal levels, I think it's a minor glitch in my system.Click image for larger version

Classic IE10 instead of Metro IE10
Hi, Sorry if this has already been asked - I'm trying to catch up with developments and it seems easier asking rather than blundering my way between Metro and Normal mode. For regular browsing I'm using IE10 from the normal Windows desktop. I find that if a program opens IE10, it opens the...
