    Hi guys, I have gotten a problem recently (idk how).
    I have been getting CPU usage of 100% when I am on gunz and when I switch tabs to any other things, the usage goes down to a very low percentage (first image is just right after I switch out of gunz). Somehow it is always the "Desktop Window Manager" that is consuming all the CPU. Any idea how to fix this?

    DWM (Desktop Window Manager) usually takes care of background things such as monitor resolution, thumbnails, theme effects, etc.

    I suggest you a few things;

    1) Change your whole system performance - click here.
    2) Upgrade your GPU (could be causing it) drivers & other hardware drivers if they are not up to date.
    3) Whenever it uses so much of your CPU, right click > Open File Location > the file should be located under Windows/System32 folder, if it's not there - it's most likely a virus then.
    4) Scan your PC with MBAM or ADWCleaner.

    I have tried out everything except for no. 4 which I scanned using Norton Antivirus and it is still not working. The surprising thing is that this only happens when I run gunz and not any other games

    Norton is not as trustworthy as the softwares George mentioned, do try scanning with them and post back with the results.
