Perfetto Debug Skill
When to Use
Use this skill when investigating VR performance issues on Meta Quest devices:
- Frame drops, jank, or stuttering
- CPU or GPU bottlenecks
- Render pass overhead and GPU utilization
- Thermal throttling and clock frequency changes
- Frame timing variance and missed vsync deadlines
- Thread contention and synchronization issues
- High draw call counts or overdraw
VR Frame Time Targets
These are the hard deadlines for each refresh rate. If a frame exceeds its target, the compositor must reproject or the user sees a stale frame.
