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...

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.
In my case the last update (15.18 - 160109) did the trick. CPU-usage 0.1 in idle state (large file) even with checked checkbox of "Check grammar as you type" under the "Spelling & Grammar".
It doesn't for me. Same as before.
Does Microsoft even regard this as a bug? Maybe they think 50+% CPU is the price you pay for active grammar and spelling checking. If so, please just say so. It is the deafening silence that is the worst and makes me doubt the future of MS Office.
I signed up to Microsoft's new service model in order to support them. I like the companies that support key software that I use to be financially viable. But it looks to me that MS Office is destined to go the way of the dinosaur. If this isn't fixed soon
We all reported this issue. Multiple times. I mean, we are in 2016 and a word processor runs at full CPU when composing a single page document? Surely, someone must have noticed this issue. Yet, it has not been resolved in months.
