Ever since I updated to Substance Painter v 12.1.0 build 5529 I've been having performance issues. Especially when saving larger files and painter hangs when I try to close it.

I have updated to the latest substance painter version and there’s an issue where painter abruptly takes up high cpu and gpu usage even though there aren’t any procedurals or any sort of layers added to any object, it also fails to close properly upon closing and just stays in the background causing huge cpu gpu usage hikes and I am hitting 85 percent on 64 gigs of ram while working on nothing!. Please fix these issues and also, your substance assets library is so damn laggy while trying to load up anything, if I change icon sizes, that is causing me to wait 5 mins almost for it to stop lagging and respond properly. PLEASE FIX THIS!

Also, my specs, 
Ryzen 9 5900x
Rtx 3080 10gig
64Gb DDR4 Ram
Installed on NVME SSD

same here , super low performance ,very long to save projects , and some projects were crasshing when opening them. after updating with yesterday nvidia drivers , the crash stopped , but the lag is huge and cache usage much higher.

rtx 4090 all drivers updated 64gbddr5, 14900kf cpu,2TB Samsung 980Pro 

Same here, saving files takes upwards of 30 seconds for a very simple project and minutes for more complicated one.

Latest Studio drivers, R7 9800X3D, 64GB DDR5, RTX 4090, 2TB Samsung 980Pro (with plenty of space and health).

The VRam usage is also astronomical, on the simple project (im talking like 5~ fill layer, no generators/filters etc) it will use all 24GB Vram and 40+ GB of Ram just to do a single stroke. Its almost unusable in its current state.

Hi everyone,

Depending on the hardware, we’re indeed facing significant slow downs and we’re working on it. We’re sorry for the inconvenience and we’ll let you know as soon as the 12.1.1 bugfix is out.

I’m experiencing the same issue.

After updating to version 12.1.0 build 5529, saving files now takes an extremely long time. GPU usage has also become very high while painting, causing a lot of lag and stuttering.

I hope the official team can address this issue as soon as possible, as it is seriously affecting the Substance Painter user experience.
