Version reorganizes casting, presets, GPU, CPU and memory. See how to transform performance capture into quality gate.
Direct answer
On September 16, 2026, Meta published Meta Quest Developer Hub 6.5.2 with redesigned casting, named presets in Performance Analyzer, optional GPU profile, and new metrics for CPU, memory, and GPU command batches. The version also allows capture via the `mqdh-perf capture` command. Measurements help to locate bottlenecks, but they need a reproducible scenario, target device, controlled heating and approved limit to become a release criterion.
Preset gives context to the capture
Naming configurations reduces comparisons between runs with different parameters.
Optional GPU avoids invisible cost
Instrumentation can alter performance; Enabling it only when necessary improves reading.
CLI brings performance closer to CI
Automated capture allows you to save artifacts and detect regressions before the candidate build.
Casting is not equivalent to the final frame
Streaming helps observation, but can introduce load and does not replace metrics on the device.
Nexus Reading
Standardize scene, duration, temperature and headset and only block confirmed regressions on repeat.
FAQ
What has changed in Performance Analyzer?
Meta cites named presets, GPU opt-in and additional fixes and metrics.
Is there command line capture?
Yes, the version documents `mqdh-perf capture`.
Is a single capture enough?
No. Thermal and load variation requires repetition and controlled context.
