What problem does it solve?

egui's immediate-mode architecture hits performance ceilings. This skill explains why it occurs and how it compares to retained-mode alternatives, offering actionable optimization guidance.

Core Features & Use Cases

  • Core Cost Function: per-frame work scales with total_widgets; every frame runs a layout pass and a paint pass, with per-widget costs and caching help.
  • Performance Thresholds: presents typical widget-count thresholds and headroom to guide optimizations.
  • Use Case Guidance: practical strategies to reduce nesting, minimize text, and optimize paint commands in egui apps.

Quick Start

Analyze a given egui UI to locate widgets causing layout and paint load that prevent 60fps.
