Using the DH61AG motherboard onboard graphics with the latest Intel drivers, Task Manager showed unusually high CPU usage (up to 30%) by System (NT Kernel & System) when watching movies. I tried this without the onboard graphics and CPU utilization went down to roughly 0 for System. Using Process Explorer, I've tracked it down to ntoskml.exe!WheaAttemptPhysicalPageOffline+0x350 and dxgmms1.sys. I believe this is the Intel graphics driver making a DirectX call to page system memory. If there is a way to fix this or if I have to wait for a driver release please let me know.
The processor is an i3-3220. I have tried driver version 188.8.131.5232 and 184.108.40.20671. I have tried this on multiple systems with the same result. The other systems also have i3-3220 processors.
We recommend you to uninstall the graphics driver from your system, and then try to install the version from the Graphics site, Version 220.127.116.11.3071 from March 22, 2013.
Intel always releases new drivers' versions, so you may want to check our site in the next couple of weeks.
I installed the new diver. The issue still exists in my PC. Have you set any special properties for graphics driver ? My processor is i5-3450, the same issue in i3-2100.
