  • MX780 Constant CPU Usage

    I am trying to find an older post related to this, but the search in this forum does not work well. It seems to return 0 results when I have more than 1 keyword.

    I was wondering if there has been any progress on the issue of the MX780 mouse driver "App.exe" constantly using the CPU at minimum of 2 or 3 percent. This is simply unacceptable. Whenever I reboot my computer, the first thing I do is go into Task Manager and kill the driver. I heard somewhere that the driver was written in .NET which is probably part of the problem. Should be C/C++.

    I saw that there hasn't been an updated driver since February of 2017. Is this product still being developed???

    Any update? This is discouraging.

      Any update? I just noticed that a coworker of mine was using the same mouse and we checked his Task Manager as saw App.exe was using 5% of the CPU with no mouse movement! This is totally unacceptable! Can someone please reply to this issue????
