high cpu usage after latest graphics driver update (nov 2014)

[GCobe]

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 : /message/257256# 257256 https://communities.intel.com/message/257256# 257256

Thanks,

I also have this problem as described above. Built a new PC a few weeks ago with an i5 processor using integrated graphics and running Windows 7. Installed the latest drivers. I have multiple users frequently switching on this PC (family PC). I regularly find the CPU is thrashing with one or more disconnected sessions running an instance of igfxem at 25% CPU each. Happy to provide more details if requested. Installed the older drivers last night, no recurrence so far.

I have the same problem with my PC (ASUS Q87T with i7-4785T). after installing the latest drivers, igfxEM consumes 20%+ of CPU. (file has the same version as in the screenshot).

While waiting for an update, I don't think there is any problem if you just kill the process if it misbehaves. Or are there any side effects?

I was killing off the rogue processes with no obvious issues arsing, but that gets tedious after a while. I manually installed the original driver a couple of weeks ago & I have had no recurrence of this issue. I recommend you do that, just make sure you don't accept the optional update via Windows Update until there is a fix available.

I have the same problem after using Intel Driver Update Utility to install new driver.

Windows 8.1 64-bit

ASUS Z-87 Pro mobo

Same problem with Intel NUC i3-4010u with latest graphics driver (and latest BIOS). I will try an older driver for now as well.

I'm having the same issue with Alienware 17 (Intel HD Graphics 4600 + NVIDIA GeForce GTX880M)

I'm having the same problem with Xeon E3 P4600 graphics. There's a new driver build just released, the problem might have been fixed. (I can't test as the new build doesn't support P4600 unlike the older ones).

Thank you for being responsive!

I have this same problem, except when I try to install the latest driver I get: "This computer does not meet the minimum requirements for installing the software".

I assume it's because I'm not actually using the IGPU but a dedicated video card (system is i7-4790K+Z97+16GB RAM, so should be powerful enough for minimum requirements ). Anyone know a way to install the update to fix the problem other than re-cabling onboard back in?
