until 2 months ago I had Windows 10 on my old PC and Bambu Studio as well as my Widnows system was working very well if Bambu Studio was open.
Now, with my new PC (much better hardware than the old Windows 10 PC) and Windows 11, whenever I have Bambu Studio open, the whole Widnows System and all other open applications get very slow. As soon as I close Bambu Studio everything is working fine again. I tried it serveral time and I can 100% confirm that the laggy and slow system is because of Bambu Studio.
Is anyone of you guys facing the same issue with Bambu Studio and Windows 11?
If so, is there any solution?
Right now I have to open Bambu Studio, slice and start the print and have to close the Bambu Stuido again to work normal with my PC.
Some programs do not get on well with the newer processors. Studio can actually crash unless you restrict the cores used. It might be worth doing a search on “affinity settings bambu studio” to see if you can find a solution.
As far as I know this issue is only happaning with Intel CPU and I have a AMD 7800x3D.
But I will try to reduce the used CPU cores and see if this will help
I’ve been on Windows 11 Pro that came on my (at the time) new Mini-PC for about two years now. It smokes my old Win-7 machine. My mini will boot to my desktop in about 10 seconds. I haven’t seen the slow problems that others have seen. But then I “sanitized” my machine. There’s always way too many add-on aps that run in the background.
One-Drive is huge system hog. I disabled it. And now recently, I was able to uninstall it. MS wouldn’t allow that before. Its whole job is to read all your personal files and load them to “The Cloud” and maintain them.
Look for other “background” aps for such things as your printer, graphics and other hardware and software. I check and run updates on my own. I don’t need nanny aps hogging my machine on a daily basis checking for updates. Many, like BL and MS Office check on their own when they’re run. Even that is typically an option.
I ask you to leave the answers with “downgrade to Win 10”. The problem here is simply that Bambu Studio, and ONLY Bambu Studio, is blocking the entire system. I have tested this intensively. All software runs without problems with my PC and Windows 11, only Bambu Studio is blocking the system. So it is definitely a problem with Bambu Studio.
I still disagree. My system has no problem with Bambu Studio. So, it’s not Windows 11 and/or BS alone. I run other software while BS is running. I often page back and forth between screens. I sometimes have it running on a separate screen. I’m open to look at your proof.
As I said, One Drive is a huge hog, and it’s turned on by default in Win-11. So are many more background aps. If you want to see what is running when in your system, download Autoruns from Microsoft’s Sysinternals.
Same here. I went from a desktop to a Mini-PC and it blew my mind. Now I have a couple of them and I don’t think I’ll ever go back.
Thank you for this info, it’s been driving me crazy lately so I’m going to do this as soon as I get home.
Me too, I’ll have Bambu Studio, Fusion and other things going at the same time.
@lausi2002 It’s got to be something else or we would have seen tons of other complaints here. I think most people are probably using it with Windows 11.
It may be an issue with your graphics card. I run windows 11 Pro, Bambu Studio, with a couple instances open, and a million or so tabs open on Google chrome, I have One-Drive running and I have no issues.
I have a 6 year old win 10 gaming laptop converted to win 11 that slowed down to a crawl this year due to the what seems like endless large Microsoft updates.
It’s really difficult to identify just what slows a computer down but I was running at 100% disk for a long time. Converted to an SSD which sped everything up. Yesterday I reloaded win 11 in about a half hour due to update errors. Something that I couldn’t have done before.
So if you think programs are slowing your system down, look at Microsoft.
Count me as someone who sees no system impact from BS.
I have this problem too.
I used to use win 10, I switched to 11 about 2 weeks ago, everything is perfect, EXCEPT when Bambu Studio is running. When it is running, the machine often slows down to the point that the file manager window also freezes, or I click somewhere and have to wait 10-15 seconds.
R5 5600 + 32 GB DDR 4 + 4070s
This is my machine so far, and I emphasize that apart from that, everything works perfectly with win 11.
Thank you for your comment and it profes that it is a Problem with Windows 11 and Bambu Studio.
Since Bambu Lab will be a state of the art company, this should be investigated asap and of course be fixed.
I wouldn’t suggest to raise any hopes on Bambu being a state of the art company…or that they’ll investigate anything, if something at all, and definitely not asap.
But if this belief helps you keep a positive attitude and not lose your trust and good sense, then by all means, do so. I wouldn’t, but on the other hand, I do know better (more experience)… In any case, good luck solving your Studio interface issues with Win11.
I’m running a system I built maybe 6 years ago with Win 10 Pro. It’s been upgraded to Win 11 Pro (a couple of years ago). The same old 2070 RTX, i9-9900K and 64GB of DRAM as when I first built it.
I just popped open Studio to see what it did. After about 10 seconds, it did exactly what it should have done, which is basically go completely idle.
If your system slows to a crawl with Studio open, you need to open Process Monitor before you start Studio and take a look at why. There are many parameters related to process behavior that can be monitored, any one of which might be a clue.
I would say the issue is more likely to be a problem with the configuration of the machine than a fundamental problem with Studio. Studio is trying to do something that it quickly succeeds in doing on other computers, but that takes it forever on this computer. It’s the computer’s behavior that’s the problem, Studio just happens to be doing something that “excites” it…
@RocketSled I don’t understand where you’re seeing that your computer is going idle. I’m not doubting that something is slowing it down but that screen grab of processes & BL studio doesn’t support that Studio is causing the slowdown. To me it shows minimal impact.
For those of you experiencing this, is Orca slicer doing the same thing?
My system shows 386mb of memory and no CPU or disk usage by opening up studio. It took my overall memory from 44% to 48%. I have 20gb in this computer. So I don’t see anything here to complain about unless your memory is maxed out.
As I said before Microsoft is running a lot of stuff these days. I’m at 48% of 20gb and only have Edge, chrome and Studio running.
I don’t understand where you’re seeing that your computer is going idle
Right click on the task bar and open Task Manager. Then open Studio, it’ll show up in the Apps section of the list and you will be able to see how much work Studio is doing with the CPU, memory, disk and network. If one of these goes to a very high value near 100% it will be a clue as to the problem on your PC.
