15% CPU usage at idle Inventor 2018

[COLINBRUSCHI]

Hi All,

Inventor 2018.1.2

With any IPT, IAM or IDW open I'm getting a constant 15% CPU usage from Inventor, this usage drops off once the file is closed while still having Inventor open. Any ideas?

Have you restarted your computer and see if that stops?

Running any non-default addins? 

[COLINBRUSCHI]

Yup, numerous boots have been done since I noticed this. I've tried disabling all add-ins thru the add in manager, then restarting inventor with non of them running, still getting this CPU usage at idle. Other users here don't seem to have this issue.

@COLINBRUSCHI

Are your files stored locally or on the network?

Here's a few things you can try..

1.  Disable your anti-virus application and try again.

2.  Are you using a VoIP phone in your office?  If yes is your machine connected directly to the phone or the jack on the wall?

3.  If all of your files are locally, disconnect from your network and launch Inventor again and test.

Is it the actual Inventor EXE?  Or is it a Chromium Host executable?

@Mark.Lancaster

We use vault but files are local when working with them.

Yes we use voip phone system thru network, but disabling the phone app and disabling the LAN connection & restarting Inventor shows no difference.

I cant disable anti virus since its admin managed but everyone uses the same program and no issues.

Hi Colin,

If possible, could you share your machine spec? Start up Inventor and open a part. Go to Tools -> Application Options -> Hardware -> Diagnostics -> copy and paste to a text file.

Many thanks!

Hi! Many thanks for sharing the hardware profile! It looks very nice. I don't see anything wrong with it. It is actually better than my desktop machine. If you close Inventor and restart it, does it still stay at 15%?

Thanks again!

[COLINBRUSCHI]

Yes I have restarted numerous times.
