Set up performance budgets and custom rules with 3Lens.

Configuration Rules Demointermediate

Loading example...

Define performance thresholds, create custom validation rules, and get automatic warnings when budgets are exceeded.

Features Demonstrated

• Performance Budgets: Set FPS, memory, draw call limits
• Custom Rules: Create application-specific rules
• Violation Alerts: Get warnings when rules are broken
• Rule Composition: Combine multiple conditions

Example Rules

const probe = createProbe({
  rules: [
    {
      name: 'max-triangles',
      check: (stats) => stats.triangles < 1000000,
      message: 'Triangle count exceeds 1M budget'
    },
    {
      name: 'min-fps',
      check: (stats) => stats.fps > 30,
      severity: 'error',
      message: 'FPS dropped below 30'
    }
  ]
});
