Hi Guys, just to let you know that the final version of Office does not work properly and have 70-100% CPU issue as reported on numerous posts here. In my case, it's the WORD with which I have the issue with and no remedies posted here help. Please provide the fix as soon as possible, because this bug renders the new suite useless...

Hi,

To resolve this issue, is your installation of Office for Mac fully updated?

In any Office application go to the Help menu and choose Check for Updates to launch the Auto Update app. Let AutoUpdate install the updates and then restart your Mac.

Update us with results for further assistance.

I'm having the same issue on the same software versions.

It's a large document ~130 pages with a lot of tables. Typing and scrolling are both laggy and I'm frequently getting SBBOD when I change a style (e.g. set a highlighted section of text to bold takes ~5 secs).

CPU usage is <1% when Word is in the background, but bring it to the front and CPU is >50%. It jumps to 80-110% when typing or making changes.

I have the latest Word for Windows in a VM with a fraction of the resources allocated and am not seeing the same issues with this document. 

Changing to Draft view has sped up scrolling and improved typing lag somewhat, but the high CPU usage remains.

UPDATE: updating to the latest fast preview (15.31 161227) has fixed the lagginess, but still experiencing 40-50% CPU when typing. At least it's now usable.

    I installed the latest version (15.25) but I still have Word using 80-100% of my CPU as soon as I start scrolling down the file, and being very sloppy. The file is not too big (8MB), and it is about 27 pages long with 8550 words, 3 figures, formulas and endnote references, definitely a reasonable size file.

    My Mac is running El Capitain 10.11.6 with a 3.1 Intel core i7 and16GB of RAM.

    I tested in Office 2010 for PC (running in a virtual machine on my mac) and it does not affect at all the CPU. Also the same file is very smooth to scroll with pictures and endnote references.

    There has been an improvement with respect to the previous versions, but definitely not satysfying for a word processing program! How much CPU do you need for a program that was already running on Mac with 1 MB of RAM at 8 Mhz?
