Hi,
I am running an ASUS laptop with Windows 7 and I also see high CPU usage by "igfxEM.exe", one instance for each opened user session, exactly since the Intel driver update.
Each instance is using a CPU thread at full speed (12,5% of total CPU on my Intel i7). See attached screenshot with driver version number and CPU usage display.
I believe this is the same issue that has actually not been solved :
Thanks,
Grégory
