Fusion 360 8GB RAM usage when stationary 44GB usage when designing

Hi, I am seeing some very strange behaviour with fusion 360 and its RAM usage. See image attached, when stationary i.e. no design open - just launched and sitting, fusion is using 8GB of RAM? Why is this?

What's worse is when actually designing, it shoots up between 30GB - 44GB of ram usage..... I have a powerful computer I9 13900K and 64GB ram, didn't buy the PC specifically for Fusion, but I expect to be able to use my PC for other things alongside fusion with my given spec, but fusion is taking up more than 50% of my resource, surely this cant be right?

Hi @ezekiel.brooks89,

 

8GB idle is definitely too high - I get about ~1.5GB usage at launch.

 

Do you perchance have files stuck in your upload queue? Perhaps there is data being pulled up in an attempt to upload. If you would please, confirm that all your files are saved and present on the cloud and look as they do on the desktop client? If all looks good, you may safely attempt a Reset using the Service Utility, which should purge any cached files.

 

When it comes to RAM usage mid-modelling, that is less concerning depending on what you're working on. If you have a very complex assembly or parametric history, I have occasionally seen cases where utilization bloated depending on how models were referenced and usage of bodies versus components. If you are able to share an affected model, I can attempt to load it here and check for similar consumption; otherwise I would just take a quick look at your browser see if there is any redundant data being loaded that could potentially be replaced with a duplication, and see if that cuts down usage at all.

Hi @ezekiel.brooks89,

 

I asked around and it sounds like there are some reported memory bloat bugs related to specific workflows that will be in a future release. I'm not sure if they are the cause of your high memory usage, but you should hopefully see some decrease over the next few months.

Excellent, thanks for the heads up, hopefully this solves the issue.
