Hi there, I got a weird problem. I tried to record my screen using different screen recording applications like Camtasia7, Hypercam, and some others. So if I hit "record" everything works fine for about 3-4 seconds. Then the PC slows down heavily caused by extremly high IO usage. The PC gets nearly unusable and laggs like hell. I can't switch applications, can't get TaskManager with Ctrl+Alt+Del, or something else without waiting 1-3 Minutes.

After about 5-8 Minutes and a bit of luck I am sometimes able to end the process of the recorder and IO calms down very slow(100% IO lasts for about 2 Minutes before becoming normal).

I don't know why this happens. Screen recorders that support Windows 8 aren't out afaik but at least Camtasia7 worked with Windows 8 Developer Preview and Windows 8 Release Preview (only had to change record method to .avi). No slow downs or something else.

Is there anyone out there who knows this problem too? Is there maybe a solution to this problem?
