Speed up autocad

[rustysilo]

I always set up any computer I work on for best performance in the System Properties (right-click My Computer > Properties > Advanced tab > Performance > Visual Effects tab > Adjust for best performance). I doubt this would help very much with your situation since you are working with multiple attachments, but it may.

It is just a friendly suggestion. We welcome you to CT and encourage your continued involvement.

Good point, I will start a new thread with the same question and responses to ReMark's questions in that.

Speed AutoCAD up, a few things to try, I am sure there are others.
Options> Open and Save > Turn off display digital signature information
Check in layer manager to make sure you don't have 100's of layer filters, if so delete them.
Check the scale list to make sure you don't have 100's of scale lists.
Don't use true type fonts (TTF) and see if that helps, lots of those will slow things down.
Go through the file paths in Options>Files and make sure every single path listed
actually exists, be meticulous.
Dock the command line in the lower or upper portion of the autocad screen.
Close the new layer manager in 2009. Use LAYERDLGMODE set to 0.
Use -purge, Regapps, purge all.
Clean empty groups and unnamed groups out of drawing.

That is an excellent list of suggestions you've put together. Thank you.

Thanks, I have updated it based on other things I have remembered and or have read since this thread started.

Does your computer have Blue tooth? A user reported a blue tooth phone placed
near the computer slowed the computer to a crawl, they moved the phone away and
it sped back up.
Manual Tune video driver - Options, System, Performance Settings, Manual Tune,
Driver Name pulldown. Which one is showing? For vista Direct3D might be better.
For XP pick the driver for your card, mine is from nVidia so I have nvd3d9.hdi
picked. Pick the Enable hardware acceleration to see if that helps. Further
down move the sliders over to the left.
Viewres still affects the speed of the computer, contrary to what you may have
been told. Autodesk has confirmed this to me personally, especially so with
MEP. Set it to 500 instead of the maximum setting.
Set ltscale to the proper value, a large drawing with linetypes will slow down
when in MS with ltscale set to 1 or a small value.
Set the virtual memory paging file to a larger size with a min and max rather
than letting windose handle it for you. XP - Control Panel, System
Properties, Advanced, Performance Settings, Advanced, Virtual Memory Change,
Custom Size, Initial size = 3X ram (3GB ram = 9GB paging file size), maximum
size = 4X ram. Go larger if you have the hard drive space.
In the same area as immediately listed above, instead of Advanced tab pick V
isual Effects tab, pick adjust for best performance, then if you must go to
custom and pick the few settings you can't do without.
Lower hardware acceleration setting, in Control panel, Display, settings, advanced,
troubleshoot, move the hardware acceleration slider to the left one click
and try it out, keep moving it right and watching for a change in performance
and also fewer crashes. Find a setting you can live with.
Antivirus software - disable and see if there is a difference in performance.
Go to autodesk.com web site, pick Services and Support, use the Knowledge Base
and search on "slow", "delay", etc.
Clean empty groups and unnamed groups out of drawing.

One more I remembered.
TREEDEPTH at -2520 and SORTENTS at 20, or turn SORTENTS to 0 if a large file
and using draworder.

[ReMark]

That is impressive. I am going to print it out and tape it to the wall next to my workstation. Great work!

What is the max physical RAM limitation on your computer? 4GB?

32bit OS, so 3gb is kinda the max.

[Bogbadbob658]

I found that changing the 'Layout Region Option' to 'Regen when switching layouts' (found in options, system) helped. Before changing this my machine would hang for ages. Hope it helps.

[OMEGA-ThundeR]

A setting that was allready enabled, so no effect.
