Performance API

ExoJS exposes practical runtime counters through renderManager.stats.

RenderStats Fields

• frame
• submittedNodes
• culledNodes
• drawCalls
• batches
• renderPasses
• renderTargetChanges
• frameTimeMs

Application resets stats each frame via renderManager.resetStats().

Example

const stats = app.renderManager.stats;
console.log(stats.drawCalls, stats.batches, stats.culledNodes, stats.frameTimeMs);

Benchmark Harness

A repeatable baseline benchmark exists at:

• test/perf/rendering-benchmark.ts

Run:

npm run perf:benchmark

Use this for before/after performance comparisons in renderer/runtime work.
