Substance painter performance degrades after a few minutes from opening.

[MFM-Art]

Hey there!

Ive been having an issue past couple days coming from no where, my performance just tanks and makes both the camera and mouse movement very jittery. Can't put a finger on what it could be as I've never had this issue before and my ram/vram are barely touched, and nothing else seems to be bogged down on my computer so I'm assuming its exclusive to substance.

and here is my rig information just incase 
GPU: RTX 3090    Driver 512.15
CPU: Ryzen 9 3900x
RAM: 64 GB 3600 Trident z
Everything is running more or less stock on windows 11.

Hi,

Could you check that your cache folder is not full? Otherwise, can you try deactivating the SVT in your preferences? 

I hope this helps, if you have any questions feel free to ask.

Kind Regards,

Geoffroy SC

Hey Geoffrey!

The cache was definitely not it, I cleared it out and came to the same conclusion. I will try messing with SVT later today, I tried fiddling with my Nvidia control panel settings and I'm trying to see if that has solved it first. I find it odd that SVT would be the cause as I have had this feature enabled since it was announced with out issues in the past.

I'll come back when I have further developments!

[MFM-Art]

I tried disabling the SVT feature, and it unfortunately didnt work, the issue still persits after some time. Not sure what to do now.

[MFM-Art]

Followed a post from 2015 that suggested turning off threaded optimizations in NVIDIA control panel, it seemed to solve it but I need to try through a longer session tomorrow, will report back tomorrow evening!

[MFM-Art]

Hello once again, unfortunately the solution i looked into earlier didn't seem to work in the end. I've also just tried reverting drivers to a previous version and just encountered the same issue and ive just about exhausted all my ideas on things to try.

[MFM-Art]

To add to my tests, I have tried downgrading drivers to previous versions, uninstalling and reinstalling to another drive and messing with some windows properties, still at a loss with no improvements.

I also get extreme slowdown on a Vega64 card, I'm not sure it's a graphics card issue.

Often things slow down after changing some layer properties.

Substance has always been slow / choppy compared to other 3D software. Viewport navigation often slows down. My only guess is that the way the layers + materials work is processor intensive, and something everyone encounters in Substance 3D.

[MFM-Art]

So my solution resolved itself but I'm not sure it's clear to me. I moved my cache from one SSD to my nvme ssds and it seems to have done it.

I was at 91% cache disk usage before albeit with plenty of room left (over 100gb available) and the cache is currently on a drive with several 100gb's sitting at 60 ish.

Again I'm not sure if that is what it is or if this help for you but thought I'd leave it here anyway

[MFM-Art]

Would like to add to this that my problem returned , moving my cache seemed to be temporary if it wasnt due to something else.

I know its been around a year + by now, but have you found a fix for this? I'm currently having a similar situation too, just more issues^(like crashing on launch, and not being able to re-open SP if i undock the windows to my secondary screen as i close it) and not just it being super laggy. I dont mind giving it a go too if you found a fix for it. I been trying to fix this issue for days, and I am out of ideas after looking around/ further testing SP out.  

Thanks in advance

Hello I have exact same problem. I tried reinstalling drivers and other solutions I found online also I tried solutions from this topic but nothing helps, sometimes after driver ceal reinstal + SP reinstall it helps for like one sesion then it jitters again ;c

[hiab-x]

I have this problem too. Using an RTX 3080 , i9 CPU - My Substance is the Steam edition and pretty much performs as described below. A sample project onlu needs to be open for a couple of minutes before slowdown. 3D viewport becomes unworkable. 
I'd be very interested in a solution to this, my PC can handle a great many things in 3D, VR games, Blender Renders, Unity, Unreal Engine. The only app that seems to degrade over short time is Substance Painter. 

[M24145330rvyp]

My substance painter is also extermly slow and painful to work with , turning a layer on and off takes minutes on RTX 4080.

I'm so tired...

[Ben36560514xsba]

Hey all, I've been experiencing the same issues with a 3070 and a Ryzen 9 series cpu. 

Try this fix! It worked for me strangley enough... 

1. Create a new painter file, load in your mesh and set up your initial settings.
2. Save the file
3. Re-open the file 
4. No more Lag! (at least for me) 

Hope this helps 

[lucas@gamecan]

Just any new file will do, or is the solution to start a new project for whatever you're working on?
In both cases this seems to be a cache issue, I really hope it gets fixed soon, it's been 2 years of this issue being open already. Well, there's also a post from 2015 about it but that was ages ago, it may as well be an entirely different problem now

[M24145330rvyp]

I have removed most of my layers(Sadly there is no merge layer in substance painter yet) still super slow . I have 5 UDMI. working on 2k most of the time, but sometime i need 4k so i can work on details.

Thinking about moving to Mari.

[Ростислав38901863wl0x]

Finaly, it working for me!!!!

Thanks!

[?????_6745]

Oh God, I'm so grateful to you. I've been struggling with this problem for over 20 hours and was already on the verge of breaking down.

[M38908470il0x]

Any update on this? i'm helpless, Thinking about ,moving to Mari.

[M38908470il0x]

Now i am uisng RTX 4090 and still slow on this particular project. 

[Alex3680913004dx]

i know this is a singular solution (for me) that i JUST found,. but i've had the same problem for atleast 2 years. constant stutter and freezes on a 4090 + amd 7950x+ win11.   the ONLY solution so far is  COPY THE FILE TO DESKTOP and just work off there. no folders no nothing. NOTHING else works for me (i noticed shared folders REALLY fak things up- freezing even worse etc).   i hope this works for you. 

[MFM-Art]

That sounds like it could be a drive location issue, I am on a 4090 now aswell I haven't encountered any problems, make sure you have cache set to an add, set your 4090s gpu cache size to unlimited and save files to a faster drive as well and see if that helps

Hello! Did you reinstall Windows or tweak something? Because I have same issue after built new PC(i9 14900kf, 4090, 64Gb RAM). In SP 2023, 2024 and 2025. I can work in Painter well but after hour or hour and half viewport and color picker becomes laggy like it have super low refresh rate. But everything else works fine. Even some parts of painter like ajusting colors or generator's settings. I try probably everything: run as admin, g-sync on/off, fixed refresh rate, old drivers, new drivers, studio drivers, high dpi settings, cache moving on ssd/nvme ssd/hdd, gpu cache size. This problem super rare I guess, because there are no more info in internet about this. I even try chatgpt lol. Last thing I need to do is reinstal Windows. If this issue keep persist I don't know what to do. Prob build another PC with more "stable" CPU

[MFM-Art]

I mean since my original post i upgraded to a 13900k a rtx 4090 and 96gb ram along with some new ssds.

I dont think its a stable CPU thing, I havent noticed any of these issues in a long while now. I'd recommend a fresh windows install on a good ssd. and having decent ssds for cache and saves. I upgraded my old os samsung SSD to a newer samsung NVME and currently use that older drive exclusively as cache. I dont know if that will work for you but thats mostly what ive gone through since I originally posted this. 
 My work flows are different as well I guess, I used to use a lot of paint layers and that could also have a lot to do with the issue too.

but yea def try a fresh install of windows, its not that bad these days if you are on windows 11.
