Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Blender 33 massive lag in sculpt.mp4 In this exemple: a default cube, moved on X axe, subdivided to lovel 9 (about 3 mil polygons), then modificator Mirror added. When in Sculpt mode we see massive lag even when trying to navigate the scene. Lag dissapeared after a modificator applied. Same happens when using array modificator. Lag also dissaperes if switch to other non-modified objects in the scene.

Changed status from 'Needs Triage' to: 'Confirmed'
I can reproduce a 4x slower viewport when in Sculpt mode with a Mirror modifier when compared to 3.2.

We could probably generalize #100906 (Regression: Lag in sculpt mode when navigating around an object with modifiers) and merge reports?
@lichtwerk Sounds good.
