Regression

Yes

Changing "PreWarm" parameters on VFX Graph leads to significant performance drops and freeze due to rapid changes in "Total Time"

-

How to reproduce:
1. Create a new project and install the Visual Effects package
2. Create any VFX Graph and select it
3. In the Inspector, under the "Initial State" navigate to the "PreWarm" parameters
4. Change all three ("PreWarm Total Time", "PreWarm Step Time", "PreWarm Delta Time") parameters by dragging their values
5. Observe the results

Expected result: The values are changing without any issues
Actual results: The values are changing really slow, and eventually lead to a freeze that can be resolved only by killing the process

Reproducible with: 2022.3.67f1, 6000.2.6f1, 6000.3.0a6, 6000.3.0b2
Not reproducible with: 2022.3.66f1, 6000.0.58f1, 6000.2.5f1, 6000.3.0a5

Reproducible on: macOS Sequoia 15.5 (M1)
Not reproducible on: No other environment tested

Notes:
- Reopening the project after killing the project throws "Broken text PPtr in file" and "NullReferenceException: VFXMemorySerializer::StoreObject failure." errors
- In 6.3 the values are changing without the performance drop but changing the "PreWarm Delta Time" freezes the Editor the same way
