What computers are you guys using? I’m running a MacBook Pro and I could snap in half! I’m getting into very complex designs/ASM’s and fusion lags terribly. Any suggestions?
I have a old Dell PC and a new HP Laptop ($800 version). Depending on what you are doing and your internet, Fusion can really slow down. It may not be your computer.
I would blame your design and/or your internet speed first. All (most) of the computations are done at the Mother Ship and then it is sent back to your computer. If you are doing lots of artsy things, there are lots of points. Splines use up lots more memory than simply curves.
Imported SVG’s can be monsters for Fusion to handle.

You should probably specify what model and processor your Mac Pro is.

This is a totally normal reaction.
In my world Apple product don’t exist and its awesome.
Started with just garbage windows 7 lappy that I upgraded to windows 8 and jammed some cheap used ram into it. It worked, I learned Fusion on it and ran the Crossfire Pro.
Now I have my design work station in the office. which is basically a gaming pc I bought in 2021.
64GB RAM, i5-10600K CPU (this I may upgrade to the largest Socket Type LGA 1200 chip that will fit my motherboard) 15 TB harddisks , RTX3070
Then I moved the setup I had on my Pro to my XR. I didn’t use the computer, monitor or controller that came with the XR. It is actually too bad the Langmuir doesn’t offer a version of the XR without these. Used a basic on sale gaming lappy, touchscreen and a wireless SNES controller clone .
Check this out on @Newegg:MSI GP Series - 15.6" 144 Hz IPS - Intel Core i7 11th Gen 11800H (2.30GHz) - NVIDIA GeForce RTX 3070 Laptop GPU - 16 GB DDR4 - 512 GB SSD - Windows 11 Home - Gaming Laptop (GP66 Leopard 11UG-689CA ) MSI GP66 Leopard 11UG-689CA Gaming Laptop Intel Core i7-11800H 2.40 GHz 15.6" Windows 11 Home - Newegg.ca
Being able to use Fusion at the cut table is a must for me.

I agree with the TinMan. This is my setup.
Z790 Asus with i9 14900 and a RTX 3080ti with 128 RAM.
My internet connection is one gig. Like @ChelanJim said, fast internet will keep the lag from Fusion down. It all has to go to the mothership and return to you.

Yeah, I’ve come to that conclusion too. I find myself with those “minor adjustments” needed and it takes me longer to walk to the house and open Fusion that it does to make the change.
Haven’t tried to load/run Fusion yet on Bee-Link (table PC). Maybe @Bigdaddy2166 knows if it will work for small changes and post processing…?

It will work just fine. You probably will get a video card memo on the top. But as long as you aren’t trying to simulate a 3D motion model, you should be ok.

On another note. I don’t know if you guys have ever seen the movie that’s clipped in this gif.
It’s called "Ghost in the Shell "very classic ,good anime

Crazy easy and cheaper to build your own FYI.
I use an older Lenovo for Firecontrol and post processing on Fusion 360, but I use one of the PC’s I built for all my CAD work.
Hell, even my first build is still up and running from 2008.

That one in the picture I built. I bought all the parts from Amazon and eBay. Less than 2000 dollars.
1000-watt power supply, DDR 5 /7000 RAM, 3- 1TB SSD Samsung sticks.
It is a freaking monster.

Tin, I have not seen that but it looks intriguing.
Kwikfab, I wish I had the confidence to do that.
BigDaddy, it looks like a monster too.
3D CAD software does not multi-thread so it’s important to get a fast processor and not one with lots of slow cores. CAD only uses 1 core at a time so… Here is a good option that will not break the bank. Amazon.com
Overall get 32 to 64Gb of ram and a processor with a single core speed of 4GHz + It’s worth it if you’re going to do complex assemblies. Also generating complex toolpaths can take a stupid long time if you don’t have a good rig like this.
Keep in mind that you’re doing 3D modeling. Multi-cores does nothing for you. It’s all about the sing core speed. I’ve learned the hard way.
If you got the space this is even a better option. Amazon.com It has clock speeds up to 5.6 GHz

Nice rig for sure!
DDR5 user here as well, but only 13600K
Still, plenty enough for Fallout, Doom, Forza, and other games I dabble in 
Although it’s already a good +2 years old

Fusion runs like most video games, only a single core so you are absolutely correct.
The other important factor to mention is the misuse of nomenclature like “I7” and more.
I have seen people in the group get ripped off after having purchased a “built” I7 only to find out it was a 7th Gen or similar in age.

No confidence needed, really.
Back in the days of building PC’s, you ran into stuff that wasn’t exactly standardized, figuring out the proper placement of IRQ jumpers, and more. Even then, many of us successfully built and overclocked many rigs.
For the last 10 years or so, things have changed dramatically where the hardest thing is really tidying up your wires.
Here’s my old 2008 computer running a Core 2 Quad on DDR2 ram and triple SLI
@Bigdaddy2166 might recognize some of those components if he was a nerd like me back then…
All I did to bring it back to life was buy a new PSU, throw it all in a new case, and run the OS and games on SSD’s.

I was not aware of the core speed issue. That will be good to know in the future. Thank you. @Richarddbeck83

yeah I didn’t know this either. I had my boss order a computer with
- dual NVIDIA RTX A4000 video cards
- Dual 12 core Processors (Intel Xeon Silver 4214R CPU, 2.39 GHz)
Because the individual core speed is 2.39 GHz my $6,500.00 rig is slower than my 8 year old custom built computer that I spend $1,100.00 building. 
I literally have 48 Logical processors and two massive video cards but Inventor only uses 1 core and 1 video card.
this would be great for mining Bit-Coin but 3D modeling and generating complex tool paths… Not so much. In the end it’s not about how much $$ you spend, it’s what you spend it on.

My main PC is a homebuilt gaming rig I put together initially back in 2020 on the onset of the plannedemic. I knew global trade was gonna take a hit and since most electronics are made in China and my PC at the time was one I build in 2013… yea. I’ve since upgraded the processor and GFX card and increased RAM, but the thing still runs hard.
Used it for mining while Etherium was still mineable, but since then, just use it for gaming, CAD, and running my 3d printer.
Essentially it’s:
ASUS ROG x570 Crosshair VIII Hero (MOBO)
AMD Ryzen 9 5950x
Corsair H115i AIO Cooler
MSI (NVidia) 3080 Ti 12GB Suprim
64 GB of RAM
512 GB NVME main drive (windows)
1 TB NVME 2ndary (programs)
1 TB 2.5 SSD (storage)
850w Seasonic PSU
Games like a champ, although noisy when things ramp up

Mac mini on the machine a new Mac Pro on fusion
Why? The whole MAC thing just adds to all the confusion—your call. I warned you.
