Hi, I'm experiencing deep lag and slow performance with AutoCAD 2016. My work's IT support can't find what's wrong and it's been going on for months now. Here's my PC specs:Windows 7 64 bitsIntel Core i7-3770 CPU @ 3.40GHz 16Gb RAMNvidia Quadro K2200 All drivers are up to date and as you can see my PC specs are more than enough to run AutoCAD 2016. I've tested most of the "Slow performance" topics online and nothing worked. I just can't understand why we can't get this thing to work perfectly. I don't want to have to disable every single variables in CAD so it can perform fast, that's just unthinkable, I need the full system not 1/8 of it.  Help me please!!

What steps have been taken so far to troubleshoot the problem?Do you make use of layer filters?Are xrefs utilized?Have all file paths been verified?Does the problem manifest itself in just a handful of drawings or in every drawing you work on even a new one?What measures do you take to clean up your drawings and are they instituted on a regular basis?What is the source of the drawings?  Are all of them produced in-house or are some form outside sources?Are all drawings stored on the network?Have you tried working locally with a drawing?I could probably come up with several more questions but I will stop here.

Well either you solved the problem on your own or you gave up.  Couldn't have been that important.

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:

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.

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

"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.

Moderated forum and I've just tried to split it in parts but it won't let me either... same thing happens

Well that certainly sucks.

It seems like the message I was trying to send got approved, its up there ^^ starts with "Here it goes"

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

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?

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?

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:)Nate1432017-08-10 07:47:17
