Severe lag in big projects in the editor

HitomiHoshino

I am currently working on a sizable model project, and I've noticed that Live2D lags severely despite my PC still having lots of free resources that could be used.
Lags mainly happen when selecting layers, changing the order of objects in the Part or Deformer list, or using Undo/Redo. There is no visible lag when rigging (editing keyforms).
The CPU usage is very low, and I have around half of my RAM still free, which leads me to believe it is not due to my PC not being able to handle it.
Lowering the display quality or changing to texture atlas display doesn't lower the lag.
I would appreciate any help, as it is really difficult to work when most simple actions take as long as 10-20 seconds.
I'm attaching an example of the lag - after moving the Mouth XY deformed, I immediately press CTRL+Z so you can see how long Undo also takes.



Live2D Version: 5.2.03
OS: Windows 10 22H2
CPU: AMD Ryzen 7 5800X
GPU: AMD Radeon RX 9070 (16 GB VRAM)
RAM: 64GB DDR4 3600 MHz

The program will start lagging after using like 12 to 16Gb of ram i recommend closing entirely the program every few hours to diminish lag at minimum, also you could optimize the PSD's artmeshes as much as possible (as well as warp deformers) It is not a you problem everyone we use the program and it just works like that, other programs also lags without using 100% of the resources, similar to games as well.

Mostly of the lag happens on ram to CPU communication, you will see how a single core of your cpu (if you go to single core cpu usage) will spike to 100%... that is jsut how it works.

Telling you this as someone that have been using this program for like 4-5 years and have worked on models that have been Excessive on all possibles features.

With some colleages and friend we have tested different setups and yours lack of a more powerful CPU

The problem is that in this project I get this kind of lag immediately when opening the project (even when I'm only at around 7-8GB of RAM usage), it is not the standard issue of having to restart the program that I am familiar with already.
Also the lag that happens due to Live2D being open for too long usually affects the whole program, which is different to my issue

If it's a CPU issue, do you have a recommended one or what specs exactly to look out for if I were to upgrade?
