Bizarre SolidWorks Graphics Issue

So I've been running SolidWorks 2016 for a few weeks now, and then just last week it slowed to a crawl.

Basically it looks like the frame rate drops very low. The caveat is, is if I open up a drop down menu, it acts normally again.

I made a quick video of it: https://youtu.be/ye6C0FcTAbQ

In task manager, when it is in "stuttering" mode, cpu usage is 5-7%, when i open up a menu and it's operating normally cpu usage is 15-16%. Additionally I do not have this issue with 2014, it runs fine. 2015 does have this issue though which is why we skipped over it in my company. 2016 decided to just develop this problem for me only last week.

Computer: Lenovo W540 with K1100M gpu and integrated Intel HD 4600

Stuff I've tried:
  • Completely uninstalling and reinstalling all graphics drivers with the ones from Lenovo (official optimus drivers) as well as the official ones from Solidworks and the latest ones from NVidia. No change.
  • Repairing 2016, uninstalling 2016, reinstalling 2016


Any advice would be great appreciated!

Do you know the registry trick? basically you rename the solidworks registry and reopen SWX and it will create a brand new one. If the problem disappears, there is some setting that is throwing it off.

If the problem persists, you rename the registry back to the original name and reopen swx and it will be using your old registry again.

next is to use the copy settings wizard and save your personal settings. Then get the settings from a coworker who's computer isn't doing this and install their settings to see if it is related to the settings.

If you are on subscription, your VAR may already have an answer for this issue.

Hey thanks for the advice. I did try the registry trick and have talked with our VAR who has posted the question to SolidWorks as they weren't able to help.

I think it's something specific with Lenovo's drivers as I saw someone posting about a similar problem with a W541 laptop.

I'll give the settings wizard but I'm not too hopeful on that helping lol...

Thanks for the tips though!
Cheers,
Mike

Solved the problem. Basically the Macrovision FlexLM licensing software some how got messed up, maybe from the multiple versions of solidworks I had on the computer or something.

What I missed noticing previously was that when it was stuttering it was also at 100% hard drive usage and the fnplicensingservice64.exe was the root cause of it underneath ntoskrnl.exe

I fully uninstalled everything related to solidworks, the licensing manager and FlexLM / Macrovision including everything I could find in the registry as well. Then once reinstalling solidworks 2016 it's back to being smooth!

Hope that helps someone else!

Cheers,
Mike
