I have test the GPU, worked with AMD Support AND support with the manufacturer and a PC technical agent.

All found the fault to be with Adobe Substance Painter.

I have been able to bake 4k textures for my projects but I can't even paint or do anything because the program with lag and become non-responsive when I interacte with the viewport.

I have been trying to get help from Adobe Technical Support since three weeks ago and recently tried to get help here.

I'm posting in hopes of getting help.

All other support team options have failed and I when I tried to go into a call and have assisstance, the person didn't seem to know what to do.

Please help.

I don't want to pay for a subscription to something I can't even use.

If there were other options I would have never bothered with this buggy program and lack of support.

I have evidence to support that the GPU is fine and I can provide dxdiag and sysinfo if needed.

Hello @celestial_interest4076,

I've received your e-mails and thank you for it.

The thing is I don't see anything too suspicious... I'm still investigating because we currently face a "kind of" similar bug that could be related to your problem. In the meantime, could you try to deactivate the Hardware support acceleration

Edit > Settings > General > Sparse Virtual Texture

Honestly, I doubt the problem comes from there, but it's still worth checking.

I'll keep you posted.

Hello Cyril,

I have the most up-to-date driver for my GPU, I checked.
I also uninstalled all Adobe products and reinstalled Creative Cloud and Painter before taking the logs today.
The log is sent to your email, I also emailed you before with the project file and video.
Hope this helps.
I can see it is looking specifically for an NVIDIA product and failing... Not sure if this is the issue?

Hope to hear from you soon. Here or email, whichever is best.
Thank you for your time.

Hmmm, I didn't realize that your Painter was also lagging with sample projects. First thing, I'd try the basics and update my GPU. Quite often, the fix is as simple as that.

In addition, I'd like to take a closer look at what's happening in your Painter. Could you send me your log (Help > Export log...) so I can investigate on my end (still cdellenbach@adobe.com).

Let me know.

Hello,

Sorry if I seem frazzled; I've been at my wit's end with this.
I have attached a video to show the problem is with all projects meaning that even the most bare sample given by the program itself is showing issues.
There is also a screenshot of the system performance during a period of the program lag 'not responding' to show that it isn't a performance issue.

I hope this helps show what I mean about not being able to do anything.

Hello @celestial_interest4076,

Your GPU isn't the problem indeed. However, for performance issues, this is complicated to me to troubleshoot without the project itself. Would you be ok to send me your project at cdellenbach@adobe.com so I can take a closer look?

Keep me posted

Sorry, I have grammical errors; I'd edit it to be more clear but there is no option.

For reference I have an AMD Radeon RX 7900 XTX on Adrenalin 25.9.1, Windows is updated, Adobe Substance is the latest update.
