Autocad 2013 Xforce Keygen X64 Processor
Lina Neiffer
I'm not sure how long this has going on, but it's something I just happened to notice yesterday and today:
AutoCAD 2018.1.1, with no drawings open, is using a little over a full processor thread (10%-12%) while it should be sitting idle. It doesn't happen right away, but if it's been sitting idle for a little while (an hour maybe?) then sure enough it ramps up.
My full spec is below, but the i7-8700k has 6 cores, 12 threads, so I haven't noticed a performance hit. At the same time, I don't want to be burning a processor core all day long and reduce the life of the computer for no good reason. Interestingly enough, since a fully utilized thread is only 8% of the full processor load, it appears AutoCAD seems to be running a multi-thread process while sitting idle.
Let me know if you've seen this happening and if there's any solution. Thanks
It does seem that the problem originates with an open drawing, and then persists even after that drawing is closed. I have been monitoring occasionally today, but have not seen it crop up yet. I'm still trying to narrow the criteria down a bit. Obviously, if someone else has had this issue before and already figured it out, that'd make it easy for me.
As for your possible solutions, I've already disabled the onboard graphics. When I have more time, I'll look into installing updated graphics drivers and the Visual C++.
If AutoCAD still opened in approximately 3 seconds like v. 2012 used to, then I would shut it down every time. But even on the higher end hardware I have now, it still takes 8 seconds to open. Seems like a short time until you're wanting to get going on a task, or get a phone call from a client and waiting to open a drawing.
But, as I discovered after posting yesterday, the problem seems to originate from an already open drawing. So in that case, shutting and re-opening a drawing I'm working in a lot is not an ideal solution.
I'll post back if I find out any more information on what causes it or if the graphics card update or Visual C++ reinstall help. Doing this makes me nervous, though, because in my experience tweaking with these things is just as likely to mess something up further as it is to fix a problem.
This just happened again today, different drawing than before, and occurred within 5 minutes of opening the drawing. Closed it out and CPU usage remains steady at 10%-12%. I then closed AutoCAD, reopened it with the same drawing, and it's sat idle for over an hour with no issues. So it appears the problem is program-related and not drawing-related, but I'm still unsure of the specific trigger.
Installing the most current graphics drivers did not help this issue.
Not yet. I'm afraid to after past problems I've had with messing with those C++ installations and with all the problems I encountered changing the video drivers yesterday. It will have to wait until I don't have a big deadline hanging over my head before I experiment with something like that again.
In the meantime, I'll continue to monitor to see if I can find a common trigger to reproduce the issue. Thanks
I've noticed this problem intermittently in AutoCAD 2022 now. I'm not sure if it started right away after installing or not; I just happened to have Windows Task Manager open and noticed AutoCAD maxing out a full processor thread even though I had no drawings open and the program minimized. As before, because it happens intermittently it's hard to pin down any cause(s).
I don't notice any performance problems because of it because I still have 11 other processing threads available for use, but it's certainty generating more heat in my computer case and potentially reducing the longevity of the components inside.
The root cause was never determined before, so I don't expect any solution to this problem at this point. Just posting here in case others have the same problem. I don't recall having the issue in the 2020 version, although with it being intermittent and not having Task Manager open all the time, I can't say for sure.
Edit: I spoke too soon, 2020 did it too but it did eventually calm down. I did notice that if a drawing open in AutoCAD is opened by another application as read-only then the CPU seemed to spike in AutoCAD. The drawing is on a network share. Yes, I know Autodesk says don't use network shares but I'm not paid to work around their bugs.
No, I don't have or use Visual Studio. We do have a local file share in the office (not a "cloud" share), but I have the same issue on my home computer running files from the computer only. We're just running vanilla AutoCAD with no plug-ins.
Hi, I'd like to know if you're going to optimize AutoCAD with multicore processors to use all available resources because AutoCAD is a poor performer when it comes to using the computing power provided by modern processors (example: Double Intel Xeon Quad core = 16 logical processors) while most cheaper pro software do better.
AutoCAD supports multi-core technology only in specific areas of the product and typically set to only using 2 of the processors. It uses 100% of the resources of a single-core processor and uses a maximum of 50% of the CPU for that same operation on a dual-core computer, and only 6% of each CPU on a 16-core computer.
With that said if you use the command WHIPTHREAD which by default set to 1 which is 'Regeneration multithreaded processing only; regeneration processing is distributed across two processors on a multiprocessor machine' selection. You can change the setting to 2 or 3 if you want.
Just remember, when multithreaded processing is used for redraw operations (value 2 or 3), the order of objects specified with the DRAWORDER command is not guaranteed to be preserved for display, but is preserved for plotting.
I am familiar with the WHIPTHREAD command, but today there are no longer mono-core processors and use 2 hearts only it is very little, we are in 2019, I expect better performance of a pro software of this price. The majority of processors aim for massively multi-threaded use with a lower clock rate. Open source software uses all the available cores for exceptional performance. Will Autodesk follow or not?
AutoCAD takes advantage of multi-core where there is a benefit. But, for the most part, splitting apart a pan operation or zoom operation would not make it faster. Hatch takes advantage of multi-threading, most 3d operations take advantage, but a lot of things are slowed down by it. We do push those operations out to the GPU for better performance in graphics regen and display so having a fast video card will benefit you.
We do continue to research areas where multi-threading makes sense also. I know in the update for 2020 there is a setting GSTHREADING that you can change to 0 if you want to see some of the newest improvements (but please note that you may also see some errors in some AutoCAD products turning it on). If you want to check out the latest threading improvements (and this is mainly 3d) try it out for a few hours and feel free to provide feedback here.
I started using AutoCAD from version 14, then 2000, 2000i, and so on. and AutoCAD is getting slower from one version to another. I have a dual Intel Xeon E5520 2.26GHz quad core, 12GB DDR3 ECC RAM memory and a Nvidia Quadro NVS 420 graphics card (it's a Dell Precision certified for Autodesk products when it's purchased) that is powerful for all my applications except AutoCAD. AutoCAD 2018 is ok, 2019 is slower and with 2020 even slower.
The GSTHREADING setting is only available with the Update 1 for 2020. You can download it from your manage.autodesk.com account. It is off by default because it is still a newer item that we are testing out, but it sounds like you are interested in it so I wanted to get you the latest on it. But, yes, so new it is only available in the update that came out in early August.
My computer is old but still very powerful for all other applications, I think it's all the programming AutoCAD is to review and reinvent. The early version of the early 2000s was much faster. Now I am obliged to choose a computer with the only criterion a processor with a very high frequency, 3.5GHz to 4GHz see 5 GHz ditto for the graphics card because from year to year AutoCAD become more and more heavy (Bloatware ).

I am looking to replace my current machine as I have had a number of problems recently, admittedly to do with the drive system, but in reviewing the specs of available workstations/high end PCs I cannot decide on which processor would be best.
My existing PC is a Dell XPS with a Core i7 940 2.93GHz, 6GB 3-channel 1067MHz RAM, ATI Radeon 4850 512MB graphics annd 2 SATA HDD in a RAID1 mirror array. I am quite happy with the general performance, though when I have a large pdf underlay or a number of smaller ones, the display starts to struggle with pan and zoom.
Zeon and multiple core processors do nothing for AutoCAD, let alone LT: both programs rely more on the single processor's raw speed for the most part (3GHZ is the basic requirement, so above 'basic' would be an improvement).
