Another '' Fusion 360 running very slow '' Thread. (worked flawlessly before)

[tomasgerasimovic]

Hi everyone! 

I didn't want to create such thread, but I just couldn't solve it for a long time already, so I have no choice..

I've been using Fusion 360 for a few years now and it worked perfectly all the time and then suddenly it started to work very very (very) slow. No matter what I do, just browsing around or making basic sketch - its slow. Lets say starting sketch takes ~10s, every sketch step takes also similar amount of time.

My computer is pretty old one, but as it didn't bothered me earlier,  I think it's not a hardware problem. I use HP z400 workstation with X5550 CPU, 20GB Rams, GTX680 GPU, SSD drive..

I noticed that it started to act like that when I got Fusion notification : "Windows 8 is no longer supported by Microsoft, so we recommend to update to Windows 10 for best performance''. So I updated my Windows to 10, but it didn't changed anything. 

When browsing around Fusion I was looking at task manager performance tab and couldn't notice anything weird, no sudden performance changes in CPU, GPU or memory tabs. Max usage of those components is about ~30%.

Reinstalling Fusion 360 - DONE

Updating all the drivers - DONE

Turning  everything OFF that is associated with better graphic (in fusion 360) - DONE

Everything else works good on this PC, that's the reason why I didn't stepped with full Windows format and reinstall.

Anybody can give me next idea  before I go with full format?

Check what windows has set for compatibility mode. Toggle it.

This is a different issue, but has instructions to check on compatibility.

After Fusion update I had this problem too and used that as solution, so  compatibility mode is correct. Thank you for hint.

I am having similar issues.... everything is running VERY slowly in Fusion360.  Locking up computer occasionally, not responding.  Just tried to update the video card drivers and nothing is helping. Tried to do this compatability setting and when I right click there is no option for properties etc... 

Very frustrating...

Here is how to triage these issues:

Restart your computer

Next is it related to your design? Some designs can slow down Fusion.

• Is it a particular design
• Or any design, even blank empty ones?

Next, known issues about connecting to monitors:

• Are you using  a second monitor or a docking station?
• Are you launching Fusion on a non primary monitor?
• Are you plugged into the wrong port on a desktop?

I'm also noticing some hickups. In CAM after today's update Fusion more often than not stops responding when I:

- Create a new toolpath.

- Click on a toolpath to edit it.

- Hit OK when done editing toolpath.

- Just happens randomly sometimes about every few minutes.

What this means for me is that I'm able to get about a minute of work done, and then I twiddle my fingers for 3 minutes. Rinse repeat. I am one third as efficient as I was yesterday.

Hasn't crashed at all, just hangs and stops responding.

Design workspace seems fine for me.

Thanks for the details, what about the other questions?

That is particularly the behavior I am experiencing as well. CAM edits are taking several minutes, I opened task manager and it says power usage very high on Fusion360.  It seems to be waiting for something.  I have of course restarted the PC.  I have always used dual monitors and Fusion is on the Primary Monitor.  No Docking its a desktop PC. Intel I7 on Gigabyte MB maxed out RAM  we installed a GTX-1070 Asus video card and the drivers are up to date. 

   The model I am working on has several long pieces with lots of slots in a rectangular pattern on each of them.  Patterns were done on the feature in the model NOT in sketch space.  Have made similar parts several times and never experienced this kind of slow downs.  Just opened a new part design and imported a sketch and it is just as slow again with a completely different drawing.

     Really hurting productivity at this point.  Editing CAM toolpaths is very slow after you hit OK and even just selecting the toolpath in the tree...

Not just slow with one model, slow with 3 different models so far.

The only thing connected to this laptop is the power adapter.

Sometimes Fusion hangs for a minute, then is fine for 2 seconds (not enough time to do anything but notice Fusion isn't hanging anymore), and then hangs for another minute.

Things that cause Fusion to hang:

- Clicking on the user account icon in the top right to show the drop down menu

-  When the drop down menu opens Fusion hangs again.

- Clicking on a toolpath to edit

- while editing that toolpath

- After clicking OK to generate that toolpath

- Randomly when doing nothing

- Protecting operations

- Unprotecting operations

- Opening compare and edit

- Selecting a toolpath to move it/delete

I can't select a toolpath or create a setup on a blank new design so I can't say.

@pete if you are experiencing this slowness on one particular design, and see it in another particular design, that would not be surprising if both of those designs contain the same kind of geometry or operations.

What I asked is if you see this in a brand new, empty design, or one with just a box body. The simplest possible design you can imagine (like a box alone, just one body), does that also show the same performance?

This matters because an empty or nearly empty design will have no computational load, so it points to different problems than if you are comparing only models that have a lot of geometry and toolpaths.

[Phil.E]

@FrodoLoggins 

Restart your computer, make a box using the primitive command, have this be your one and only open Fusion design, make a setup for it and tool path. Do you see the performance is the same as when there's a big model?

Wow, thread is alive!

I still haven't solved my problem, just using way less powerful laptop as nobody got time for it..

On PC that is mentioned in first post, I'm using two monitors, but tried to leave just one - nothing changes..

Fusion working slow on empty design too. I believe full format and windows reinstall is my only option, will wait few more days for hint 😄 

[Phil.E]

It's not a problem caused by running two monitors. 

The problem is seen when Fusion opens on the non-primary monitor (Fusion bug), or uses a docking station (hardware limitation outside of Fusion control), or is plugged into the wrong display port on the back of a desktop machine (human error, hardware related). Does any of this sound familiar?

For the recent people posting here, it is still not clear whether this is related to a particular design or happens on a blank empty design also. I'm having trouble narrowing it down, and afraid there are more than one issue being reported here, so it's really hard to tell what the actual issue is at this point. What we do know is this is not a general issue for the vast majority of Fusion users. This fact implicates hardware and data, the two things unique to any particular user, but that has yet to be confirmed.
