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

    GC430FR

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

       

      Thanks,

          I've noticed some sort of problem with high CPU for the past few weeks and decided to really look into it just this morning.  I also found this module consuming my computer.  With three Windows LogonIDs all "logged on" (I flip back and forth between the three) they nearly consume up all the horsepower I have and I can get little else done.

           

          If I "suspend" igfxEM.exe with the Process Explorer, everything returns to normal.  I'm not sure whether I even have the option to uninstall this software ... or hopefully wait for a fix.

            I would need more information in regards to your system configuration:

             

            Which version of Windows do you have? 32 or 64bit.

             

            Also, the exact processor model and the graphics controller:

             

            Graphics Drivers — How to Identify Your Intel® Graphics Controller

             

            Click the Windows icon, and then right-click Computer .

            Select Properties .

            Find System Type on the Properties window, and then note the processor model.

             

            Please copy-paste or attach the Graphics report generated within the Intel Graphics control panel

              Hi Allan,

               

              The exact processor model is in screenshot from previous post : Intel HD Graphics 4600.

              The operating system is 64 bits (Windows 7, service pack 1).

              The processor is Intel Core i7-4700HQ CPU @ 2.40GHz (see attached screenshot here).

               

              Also below is a copy of the report.

               

              Thanks,

                  I have not been able to replicate same situation with CPU usage. I have installed latest driver 3960.

                  Does this problem occur with customized drivers from your computer manufacturers?

                  Does it happen with earlier driver versions? if so, please provide versions.

                    Hello again,

                     

                    This problem does not occur all the time ... but when it starts, the only way to stop it is either to "suspend" igfxEM.exe or re-boot.

                     

                    I re-booted a couple of days ago (not because of this but because I installed something unrelated and it required a re-boot), and the problem has not occurred since then and igfxEM.exe is not currently suspended.

                     

                    If the pattern repeats itself, however, I would assume that the problem will occur given enough time.

                     

                    For me, this problem seems to have started when some maintenance was applied to my system back on October 21st.  At that time, an updated version of "Intel(R) Graphics Driver" was downloaded and installed as an "optional" update in Windows Update.  The "details" from Windows Update is as follows:

                    ==================================================================================================================

                     

                    A new version of igfxEM.exe seems to have be included in this update.

                     

                    I don't know if the problem is actually in igfxEM.exe ... but when I suspend igfxEM.exe the high cpu goes away.

                     

                    So when I look into the Windows Control Panel's "Programs and Features", I see "Intel(R) Graphics Driver".  Is the actual graphics driver contained in that package?  Or is that package some "optional" software that I can possibly do without?

                     

                    If I can do without that software, I would consider uninstalling it.

                      Hi Allan,

                       

                      A few additional infos:

                      * My laptop is running also an nVidia 750M graphics card ; with latest certified drivers. The problem does not seem related to any change on that side. The problem was clearly after the optional windows update of Intel drivers, as Bob said.

                      * I believe the problem occurs when switching between users (several user sessions are opened) and/or when system was previously in Sleep or Hibernate. But I am not 100% sure.

                      * I have created a "full dump" of the "igfxEM.exe" process that was running at full speed using process explorer. It is about 72MB. Should I send it to you ? What would be the best way ?

                       

                      Regards,

                       

                      Greg

                        Agree with Greg.

                         

                        I should add that you might be able to eliminate hibernate since that's turned off on my computer.

                         

                        In my power plan, I have "sleep after" set to zero, so it shouldn't sleep ... but I did have "hybrid sleep" set to "yes" so I just set it to "no".  The screen turns off after 5 minutes ... other than that, everything stays awake (again, this is a desktop).

                         

                        I also switch between Windows LogonIDs periodically ... so that can be a source of the issue.

                         

                        I took the Intel graphics software off the tray .. not sure how to get it back....

                         

                        Hope this is helpful info...

                              I can confirm the same issue on my desktop. It started after installing the latest drivers. My PC specs:

                              CPU: i3 4150

                              RAM: 4GB DDR3

                              OS: Windows 7 64bit

                              I'm using the integrated Intel HD4400 as the primary graphics card.

                              At random occasions the igfxEM.exe process starts hogging the CPU (task manager reports that it uses about 25% of CPU). the only solution is to either manually kill the process or reboot.

                              • 12. Re: high cpu usage after latest graphics driver update (nov 2014)

                                Just wanted to report that the problem surfaced again and I had to suspend igfxFM.exe.  I eventually rebooted and all's well for now.

                                 

                                I also need to report that I was incorrect about my system not having hibernate enabled.  I recently noticed that hibernate was enabled.  That must have happened when I changed power plans.  I did turn it off in the active power plan and disabled it within Windows (the hiberfile is gone) ... but I now need to go back into my saved powers plans to ensure that hibernate is off in each plan (just in case I ever decide to use that plan again).

                                 

                                It seems that this program ... igfxFM.exe ... is being called the graphics driver, but it's not the actual name of the graphics driver program.

                                 

                                What is the purpose of this program?

                                 

                                Is it part of some optional software that we may be able to disable until the actual problem is resolved??

                                    Thanks Gregory.  I didn't think of that option until you mentioned it.  I downloaded and installed the August edition and will await further info from Allan.
