Fusion 360 gets slower?

[hato54]

I have used Fusion 360 for several years on three different computers.

2 of them is running Win7 and the other Win10. One of them is a workstation and the others used i7.

When I update the hole it takes about 5 sec!

I have tested the internet connection and it´s about 5 Mb/s and I have the same problem in offline mode.

The problem occurred for about two - three weeks ago.

You have a fairly large design history so Fusion has to recompute the entire history anytime you make an edit. Also I see that it looks like you have shadows, groundplane, ambient occlusion, and I assume all the other graphics things turn on which will slow down performance.

@johnswetz1982  thank You

I’m still learning.......

I dont know how much more it would improve performance but I would suggest doing all of you modeling separately and have one file as an assembly file. I originally looked at your file to see if you had alot of move operations instead of joints, you only had a few so I think your good there. By keeping your models separate, its cleaner and easier to work with them and Fusion is not having to compute non relevant information. About the visuals, I would suggest the John Saunders video on this very topic, The BEST Fusion 360 Computer Settings & Specs

I found that really the most helpful thing for Fusion 360 being more memory and not being in large brosing sessions with many/multiple tabs, especially YouTube tabs in Firefox 66-67..  I have W7 Pro x64 / 64bit and a i5-2400 on a Optiplex 790 and it seems to like more than 8gb RAM and a 512MB GDDR3 video card (ATI FirePro V5700).  It's done ok for the most part if anyone wants to know about running Fusion on a Dell Optiplex business class PC.  Nothing else I tried really affected the performance as much as more RAM.  I went to 12GB first, then 16GB but also faster RAM as it had 666-667MHz RAM up to 1333 now.  Yeah, it could use a video card with more memory

Although I am building a new custom PC. an ASUS Z87 Plus with a i5-4690K with 32gb of DDR3 12800, Windows 10 Pro 64 bit.  a 2GB gDDR5 Nvidia Quadro (i would have liked 3 or 4gb of GDDR5) and a 650w power supply in a Antec 900 Case..  I'll happily report any speed increase I experience in Fusion.  No, I know its not the latest components but what I needed was way more RAM, a faster CPU than the 2400 and a video card with more vRAM/faster GPU instead of anything terribly current.

Either way for now, the biggest speed increase has been more RAM and faster RAM.

One more bit of advice, avoid Save Position, it saves the position of all components at that point so creates a lot of information. you should be able to create an assembly like this without any save positions, use joints. Most if not all of your save positions can be deleted as you've actually added joints after the save position. So most of your save position are doing nothing but wasting resources!

You don't necessarily need to create all components in separate files but it's a good idea to keep all features for a component as sequential as possible. 

Here a timeline from one of my designs. Note I create a component ground it or add a joint then create all of its features. Sometimes you have to use cross references that mean you end up with features of one component overlapping features for another in the timeline, just try and keep them to a minimum. Also make sure everything is constrained, use a joint or ground all components and make sure all sketches are fully constrained, red pin in the browser.

Thank You @HughesTooling for the advise You have helped me several times before.

Thinking about your design a bit more there is one thing you should do that will definitely improve performance. When you want to add a standard part roll the timeline back near the beginning and add all your standard parts there.

As an example I was able to drag component 2 to the start of the timeline, then the bearing it contains. If you did this with all the standard components, especially the XL pulley editing your custom parts created later in the time would not make these regenerate. So it was Ok to start designing your bracket first but when you though I need a bearing or a subassembly for the motor and pulley, drag the timeline marker to the start and create new component there. Later when you need to position the standard parts just position them with joints.
