Issues with slowness and crashing acad2016

[Anonymous]

Hi,

Users are experiencing a couple issues with larger projects in AutoCad 2016. There is slowness when working with 20+ tabs of drawings, and 3D or isometric drawings slow down and often crash, or bring up warning about graphics accelerator.

Specs of PC:

Lenovo S30 with 12GB memory and Xeon E5-1620 CPU.

I've seen at times acad.exe is using about 8GB physical memory + 15GB virtual memory.

Let me know what you guys recommend for a proper solution.

Windows OS is...?
Is R2016 fully patched and updated?
What size are your DWG files? How many DWG files are open?

Your screenshot is too tiny to read...

Hi pendean,

OS: Windows 7 64-bit

User I spoke with told me there is usually just 1 file open (this one in particular is 15MB) and it's also XREF'ing a few other files up to 45MB.

With files that size, the user's experience is quite normal based on similar tasks and file sizes we do.

The warnings happen because the system is being taxed: as for the crashes, I'm not sure. Does the user save often? Does it help if they restart AutoCAD every 4-hours or so? Are there specific error messages? Are they sending in error reports to Autodesk if those prompts appear?

Writing to Virtual Memory is much slower than writing to Physical Memory, especially if the Paging File is stored on a slow hard drive rather than a fast solid state drive.  So when the computer runs out of RAM and starts writing to the paging file, everything will slow down.

AutoCAD is giving you a warning in the command line about low memory, which seems to be in line with the size of files you're working with, so I think your solution is to add more physical memory for those users, or break the files up into smaller pieces to work with.  It sounds like you'll need at least 24GB of RAM, but I'd go ahead and do at least 32GB to be safe.
