What's new in 1.8.6.2
Release Notes Enhancements & New Features - New Animation Error metrics (Average, P99) in Analysis and Report views, including a new animation error chart. The PresentMon parameters --track_frame_type and --track_app_timing are used to improve the accuracy of the Animation Error. - New frametime percentile parameters (P1/P5 frametime quantiles) - Intel fabric clock sensors (e.g. NGU/D2D clocks on Arrow Lake) based on a new IntelOOBMSM PawnIO module - New Intel PawnIO wrapper (MSR, OC mailbox) with updated Intel MSR IDs - Zen 6 standard path support, experimental Ryzen SMU support - Prefer total/board power sensors over Intel's core-only "GPU TDP" - Expanded MCP server tool set: - Capture lifecycle tools: list capture-eligible processes, start/stop captures, wait for capture completion - Configuration tools: read/write AppSettings, read/write overlay slot configurations, toggle single overlay entries, select logged sensors, edit record comments - Frametime tools: frametime time series with downsampling, stutter/spike detection - PMD tools: per-channel power summaries and time series (GPU/CPU/system power) - Sensor analysis and cross-record analysis tools - ETW buffer health status tool - Frame generation awareness in metrics and comparison tools Bugfixes - Fixed animation error chart rendering - App start freeze handling (ETW service health check, PawnIO initialization) - Zen 6 core clock handling - More robust handling of invalid PresentMon output lines - Comparison tab variances chart corner radius Platform & Infrastructure - PawnIO module updates (IntelMSR, RyzenSMU, LpcI...
