Fusion EDA Suddenly Slow

Fusion EDA Suddenly Slow



Per title, Fusion EDA is suddenly noticeably slow and jittery, while Fusion 3D is perfectly fine. I have a Lenovo Legion 7 with a 3.2 GHz chip and a 8 GB 3070 GPU and Win11 (ugh). I have never had issue with Fusion 2D being slow in the past. Below is what I have tried the following:

Restart Fusion (Multiple) - No Effect
Restart PC (Multiple) - No Effect
Update GPU Driver - Brief Improvement, then Regression
Set Fusion to Use Fewer Resources - No Effect

As you can see, it's still running slowly. Can anyone think of something else I can try? This is affecting my workflow a good bit.

Hi @nsbernar ,


Sorry for any inconvenience.


As a workaround, could you please drag the schematic file and board file out of the Fusion main window just like drag tabs of Chrome? Then the performance should be back to normal. 


Please kindly let us know whether this workaround is OK for you or not.



Best regards,

You should take note of the fact that it is Fusion Electronics that is slow, Fusion 3D works fine.
I have noticed the same.
Something to think about.......

I'm unsure of what you're saying. It would be better for me if you were more clear. Thank you.

Hi @jesper8W75R , 


Thank you for your kindly reminder. 

It's an issue that our development team is working with a fix, before the fix is ready to you, we'd suggest you use the workaround instead, hope it helps a little. Sorry for any inconvenience. 


Hi @nsbernar,


Like tabs of Chrome, you could drag out the tab of schematic editor and board editor out of Fusion main window, then you should not see the performance lag in the 2nd window when editing schematic and board.


Hope it helps. Please feel free to let us know whether the workaround is for you or not. Thanks!

Thank you for the quick response, this seems to work! Obviously it's not 100$% ideal but hopefully there's a quick fix. Thank you again.
