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,

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!

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!

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.

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.

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

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