The app always slows down after a certain amount of time.

Hello

I have a question. When using Substance Painter, I can use it without any lag for the first 15-30 minutes after launching the app (up to about 16 seconds in the attached video).

However, after a certain amount of time, the app starts to slow down.

Specifically, whenever I use Alt+left click, Alt+right click, or any other combination to move the viewpoint, the initial response stutters and slows down (starting about 20 seconds in the attached video).

This also occurs when I reduce the resolution to a drastic level, such as 128.

After this occurs, restarting the app and opening the same project always fixes the issue, but the lag returns after a certain amount of time.

This "initial response slowness" issue sometimes occurs when changing transform values, etc., while using AE.

This issue occurs regardless of the project or resolution. Could it be due to cache or Autosave settings?

The specs are as shown in the attached image, and when I check performance in Task Manager, there seems to be ample processing capacity, so I don't think it's a spec-related issue.

I would appreciate it if you could let me know if there is a solution.

I'm using a regular mouse, not a special mouse or pen pad.

The same issue occurs whether I use rpero or a similar project, the sample Meetmat, or my own original model.

I tried disabling "Hardware-Supported Acceleration" in Edit > Settings > Sparse Virtual Texture, but the issue persisted.

Also, regarding the resolution, I usually work at 2048, but the same issue occurs whether I use 512 or 1024.

I would be very grateful if you could help me.
