Excel Office 365 2016 So Slow that I cannot use it

I upgraded five personal household computers to Windows 10 last week and upgraded my Office 365 subscription to 2016.  Now all five laptops are having major issues running Excel.  Excel is very slow moving between cells and when I copy a large amount of data to new sheet, I have time to play a round of tennis before Excel responds.  Excel is too slow to use anymore.  

I have researched the issue for past 7 days and tried every recommended fix without success.  Apparently a great many users are having similar issues with Excel Office 365 2016.  Preparing to try out Google Docs spreadsheet... anyone using that?

I even brought an old PC out of mothballs with Windows 7 Ultimate but when I installed Office 365 2016 Excel had same slow running issues.  I suspect my Excel problems are in Office 365 2016.  How do I revert back to Office 365 2013? 

I am surprised Microsoft launched Office 365 2016 with this major issue on Excel.

    Hi Bob

    Disabling 'hardware graphics acceleration' makes Excel 2016 work properly on my Win10 machine. 

    Re-enabling it makes the problem return.

    Rodel, you already have your answer, turn off Hardware graphics acceleration.

    If ensuring you have all current Office and Windows Drivers updates then, NO, there is no other fix for the problem at this time.

    I have this issue today with using Excel files saved in O365. I open them on the PC using the locally installed copy of Office 2016. This seems to only be happening with very large Excel files.

    A work around is to move only the large files off of O365 and onto a network share. I will continue doing this until these large type of Excel spreadsheets don't freeze up while being used in O365.

    Your hardware specifications are much more than adequate to run Office.  The problem you are seeing is a bad interaction between the part of Word that "draws" Word on the screen and some undefined part of Windows.

    The problem first showed up in Word 2013 (I also saw it in Excel 2013). At that time the Word team had completely replaced that part, "subsystem", of Word with a "new & improved" version. Since then MS has released a number of fixes for very specific situations.

    If you read through the question you'll see there are a number of suggestions that have worked for other people. The most common suggestion is to switch the current "Hardware Acceleration" setting(s) (Either in Word and/or Windows).

    As long as everything is designed to run on the Cloud and use the Internet, I'm sure this issue will only get worse. I imagine Microsoft intends to eventually eliminate VBA as an option in Excel, for the same reason. Which is Internet security. A shame to dumb e

    verything down like this.

    When I need to do anything serious, I use my old version, for which I still have the installation disk. Remember those?
