Fusion 360 Flickers then crashes; Restarting is extremely laggy

[manuelmg9QUEQ]

Hi, not sure what's happening, Fusion 360 has been working smoothly for months but now crashes within minutes of start up regardless of what file is being worked on (sometimes before I can even open a saved project). In addition to being prone to crashing, the Fusion window now appears to be operating at <1 frame per second whereas before it was very smooth. 

Hardware:

- Ryzen 3700x

- 32 GB RAM

- Nvidia 3060ti

Windows, Fusion, and Nvidia Video drivers are all up to date. No recent hardware or software changes (again, Fusion had been working without issues until now). 

Troubleshooting attempted: Restarted Fusion, restarted PC multiple times, reinstalled video drivers, reinstalled Fusion, followed Troubleshooting form (including limiting graphics, switching to DirectX 9, etc). 

Any clue as to what's happening? It looks like a video driver issue by the way the whole screen flickers, shuts off, and then returns, but restarting and reinstalling have not fixed the problem. Unfortunately, these crashes have not been generating error reports.

Any help is appreciated

Hi @manuelmg9QUEQ 

I'm not the best person to answer this, but as you've had no replies, I'll try to point you in the right direction.

The first thing I would check, is that Fusion is running on the graphics card and not on an onboard card, have a look at this article. It also contains a link to update your driver directly from the Graphics card manufacturer, this is always better than going through Windows update.

Try that and let us know how you get on.

Hi Clint,

Really appreciate that you took the time to help me out. Thankfully, I've since been able to fix the problem I was having. 

Although Fusion was running off the correct graphics card, and with updated video drivers, it was still having this terribly stuttering performance, similar to when a computer is locking up or 'thrashing' when low on memory. Apparently, it appears to have been an issue with very limited capacity remaining on the harddrive Fusion was installed to. This was causing issues with pagefiling but after clearing some space on the drive, Fusion and other similarly impacted programs are all running perfectly now.

Thanks again for reaching out
