hz-perfetto-debug

You can analyze VR performance using Perfetto traces to identify frame timing issues, CPU/GPU bottlenecks, and render pass inefficiencies on Meta Quest and Horizon OS. This Skill requires the metavr dependency and access to Meta Quest devices for trace capture.

Diagnosing frame drops and jank in Horizon OS VR applications involves analyzing Perfetto traces to pinpoint root causes, whether they stem from CPU, GPU, or render pass issues. This Skill applies that analysis to help developers optimize performance and fix visual stuttering.

Yes, the hz-perfetto-debug Skill analyzes VR applications to identify both CPU and GPU bottlenecks. It examines Perfetto traces to pinpoint render pass inefficiencies and frame timing issues that cause performance degradation on Meta Quest and Horizon OS devices.

Yes, you need the metavr dependency to capture and analyze Meta Quest performance traces. This Skill requires metavr to load Perfetto traces and execute the analysis commands needed to detect frame timing issues and CPU/GPU bottlenecks in VR applications.

You should run a Perfetto trace analysis on your Meta Quest VR application when experiencing frame drops, jank, or thermal issues. This Skill uses the trace data to identify CPU, GPU, or render pass inefficiencies that require optimization to restore smooth VR performance.

Analyzing VR performance with Perfetto traces on Horizon OS is limited to identifying frame timing issues, CPU/GPU bottlenecks, and render pass inefficiencies. It requires access to Meta Quest devices for trace capture and the metavr dependency to load and execute the analysis commands.
