Try turning off the Hardware Accelerator in AutoCad, that was the cause for my AutoCAD falling out the whole time, especially with xrefs. Is the connection to the server an Ethernet cable or wireless? I found the ethernet works better than wireless (at least 10x faster) 

Hope this helps:)

Anyone else experiencing similar problems?

Does it take long for AutoCAD to open up when first started?

Do you notice your hard drive "churning"?

Is it a platter drive or a solid state drive?

Is Windows "indexing" enabled?

When did you first notice the problem?

Have all updates been installed?

Do you receive files from outside sources and if so do you "borrow" content from the drawings to use in drawings you have created?

I have to check with my IT technician to do that. we are in a very secured corporation and we don't have a lot of maneuver.
About my way of working with CAD is there things I should avoid?! From my point of view, if I have a powerful computer and everything is up to date, I should be able to use CAD as freely as I want without any bug don't you think?

Seems thorough enough.  Did you bother to test a drawing with the anti-virus program disabled?  Some AV programs aggressively target DDL's.

Well that certainly sucks.

"Moderator" forum?  Or "moderated" forum?

If you wrote the next great Canadian novel then break it up although I doubt you could get that verbose.  Most questions can be answered rather simply.

I'm trying to post my response but the site won't let me... maybe my response is to big, it said that I’m posting in a moderate forum and it needs to be approved

Alright so here it goes:

 

Every drawing are on a server which I'm connected to, so no local, and the connection speed is superfast. Tried local but it still lag.

 

We use Xref in all of our drawing: In the Architetural.dwg, the structure is an xref and the axes are an xref in the structure.dwg. The Architetural.dwg is an Xref in the electric and mechanic .dwg

 

When it starts to lag, it's in every drawing.

 

I use these commands to clean up every drawing: _Audit, -purge*appsenReg, purge all.

 

All path are fixed. Support path are on the server and updated.

 

I have layer filters in all my drawing as well and layer states for the layouts. I also use sheets sets in all of them.

 

All my drawings are started in a main drawing where I got everything in it from blocks/Dyn blocks to layer to text and annotation style . After the drawing is created I purge out everything I don't need in it. This main drawing is 4520kB and the other drawings sizes goes from 500kB to 1600kB.

 

Here's what I did to trouble shoot the problem:

https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Cursor-is-slow-or-jerky-in-AutoCAD.html

 

Our IT support uninstalled CAD and reinstalled it. They repaired it. They tried to install it locally. Updated all the drivers. tried DirectX9 instead of 11. One of my colleague tried AutoCAD 2018 and its the same thing, slow as hell. Also switch graphic card from Nvidia Quadro 600 to Quadro K2200.

 

We also have Kaspersky antivirus running on all of our PC.
