Raw Blame History

Track Specification: Performance Dashboard (performance_dashboard_20260306)

Overview

Expand performance metrics panel with CPU/RAM graphs, frame time histogram. Uses existing performance_monitor.py.

Current State Audit

Already Implemented

src/performance_monitor.py: PerformanceMonitor class
get_metrics(): Returns FPS, frame time, CPU, input lag
Basic display in GUI diagnostics

Gaps to Fill

No historical graphs
No rolling window storage
No frame time histogram

Functional Requirements

Rolling window of metrics (deque with maxlen)
Line graphs for CPU/RAM over time
Frame time histogram
Uses existing PerformanceMonitor.get_metrics()

Key Integration Points

File	Purpose
`src/performance_monitor.py`	Add history storage
`src/gui_2.py`	Graph rendering

Architectural Constraints

60fps during graph rendering
Memory bounded (max 100 data points)

Acceptance Criteria

CPU graph shows rolling history
RAM graph shows rolling history
Frame time histogram displays
Input lag metrics tracked
1-space indentation
