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.
