We have an immersive RealityView/RealityKit scene on Vision Pro and want to measure renderer frame deadlines, misses, and per-frame CPU/GPU timing without Instruments. Apple's “Performance Trace: visionOS” instructions describe collecting a sysdiagnose for Feedback after installing a temporary logging profile and restarting. We could not find a supported local readout or field map in those instructions. Does the archive contain attributable RealityKit renderer frame deadlines, completion or miss events, and per-frame CPU/GPU measurements? If so, what supported tool, command, or export can decode them without Instruments or xctrace? Which archive member and fields contain the measurements, and what are their clock, units, and app/scene/layer attribution? A small redacted decoded example would help us verify the method before another headset run. If the archive does not provide those measurements, is there another Apple-supported method for the existing RealityKit renderer?
