Fusion Lagging on MacBook Pro

[Anonymous]

I'm facing an issue where fusion has to take a significant amount of time to "think" before doing an operation. This is an intermittent problem but the wait time is long and will show up on some basic geometry while doing basic operations. Basic operations being things like, extrude, add a reference plane, repeat a sketch operation,. Sometimes its a simple a drawing a line on a cube and after hitting ok all I get is the spinning cursor and a 30-60 second wait time.  I usually don't have any trouble opening the same part and doing the same operations on a PC version of Fusion.  Please help! 

I've tried uninstalling the version downloaded from the app store and reinstalling the version from autodesk.com. Turned the graphics performance setting down to basic settings. 

My setup: 2017 macbook pro Mojave 10.14.3. 16 gb ram,

Here is a screenshot of the part I was playing with and my diagnostic log file.

Hi @Anonymous , 

Thank you for posting!

Are you seeing this behavior for all files? If you start a new design, do you see this behavior start right away? Does Fusion ever crash? 

Can you please navigate to your graphics diagnostic and check this box. Is there any change? 

I see you tried turning the graphics performance setting down to basic settings. Was this within the preferences window in Fusion 306? There is a dropdown next to graphics driver on the general tab. 

Thanks,

This is in all files - even the most basic - and it begins right away.  The file in the screenshot is a 100mm cube and even that was painfully slow to try and add the reference planes to. I would say the slowness started after I made the extrude in the 2nd operation on that one. 

I have already selected that box in the diagnostic window, it does not make a difference.

Hi @Anonymous , 

Thanks for the reply! 

In your original post graphics diagnostics you wrote: 

Anti Aliasing: On
Ambient Occlusion: On
Object Shadow: Off
Ground Shadow: On
Ground Reflection: Off

Please turn all of this off. This is a starting point for us. 

Do you also experience this behavior on while connected to other networks? 

Can you please upload a file where you experience the lagging a lot as well as a screencast of the lagging? We need the file and screencast to reproduce on our macs. If we cannot reproduce it, then it is mostly likely your computer or the environment of the computer. 

Thank you,

Did you try the above settings?

The suggestions you made have improved the performance significantly, my system no longer hangs between operations and Fusion is drastically more responsive.  However, I discovered that saving/autosaving takes a long time to process (60 seconds+) - I wonder if this is the real root of the issue.

Hi @Anonymous , 

Glad to hear the the performance has improved! 

As for the long save times, do you still experience this while connected to other networks? You can also adjust the automatic recovery save time interval to be larger so that you don't experience it as often. 

Thanks,
