GarbageCollector CPU usage spikes when a Scene is loaded
How to reproduce:
1. Open the attached "IN-86602" project
2. Enter Play mode
3. Open the Profiler window (Window → Analysis → Profiler)
4. In the Profiler window observe the CPU Usage module and look at Highlights for any spikes in CPU usage
Expected result: GarbageCollector does not cause any spikes in CPU usage
Actual result: GarbageCollector causes a CPU usage spike (~150-200 ms in the project)
Reproducible with: 2021.3.45f1, 2022.3.51f1, 6000.0.24f1, 6000.1.0a1
Reproduced on: Windows 11
Not reproduced on: No other environment tested
Notes:
- The CPU usage spike seems to be related to Asset GarbageCollector whenever a Scene is loaded
