Hi all,
I'm having some perfomance issue's with AutoCAD LT 2014, and i cant seem to fix them.
I have tried two systems with the following spec's:
System 1
Processor: Xeon
Videocard: Nvidea quadro 4000
Disk: 7200RPM 1TB
OS: Windows 7 x64
System 2
Processor: I7
Videocard: Onboard Intel HD .... ?
Disk: 72000RPM 1TB
OS: Windows 7 x64
Both systems dont give the perfomance i need, and to be honest they both have the same performance.
I have tried the following:
- Disable AV software
- Reinstall AutoCAD
- This 'fix' : http://knowledge.autodesk.com/support/autocad-lt/troubleshooting/caas/sfdcarticles/sfdcarticles/Perf...
- Reinstalling drivers (the one provided by AutoDesk)
Nothing seems to work, the drawings zoom very slowly and selecting pieces of the drawing takes like a minute or two.
Please help,
Robert
Nope, doesnt make any diffrence.
I already toggled the hardware acceleration settings a couple of times without any improvement of perfromance.
The hardware is only part of the equation (I noticed you didn't provide how much RAM on either system). What about the data (drawing content):
- File size?
- Do you have PDF or image underlays?
- Lots of annotative text and blocks with annotation scale bloat and/or visual fidelity?
- DGN linetype bloat?
Hello
Welcome to the Autodesk/AutoCAD Forums !
Just for testing :
Can you rename AecCore.crx to AecCore.xxx
and relaunch ACAD LT 2014 and test ...

dgorsman, we recieve the drawings from customers and they work well there, no performance isssue's.
braudpat, i just did that but again no improvement in performance.
Both computers contain 8 GB of RAM.
Hello
Have you installed the SP 1 for ACAD LT 2014 ?
1) Open in RECOVER Mode each DWG (First the XREF DWGs and in last each MAIN DWG)
2) PURGE + PURGE + ...
3) Go back to the Model Tab
4) CANNOSCALE = 1:1
5) SCALELISTEDIT and erase ALL Scales (in fact as many as possible) keeping the "1:1"
6) XREF (or XR) and erase all unfound/unnecessary XREF DWG, XREF Images, XREF PDFs, etc ...
7) RESave the DWG
Waiting ...

Yes SP1 is installed, also i did the 'cleanup' on the DWG files without performance improvement.
Should the Intel HD Graphics 4600 onboard videocard be able to handle autocad ?
By that reply i meant that they have no performance issue's (The company that sends us the drawings).
All drawings are slow at both machines, so i dont think the problem is a 'bad' DWG file, but an hardware / software problem.
Thanks for your answers, the situation is that i swapped the first system (nivdea quadro system) with the second system (onboard graphic's system).
So only the system with the onboard graphics card is running, they dont work together / along.
All files are stored on the HDD of the PC, so i think network information is inrellevant because it isnt used. However its a 100Mb link.
