⚡ Bolt: Cache animation quality preset and frame duration outside render loop - #68
Conversation
…nder loop - Moved `QUALITY_PRESETS[currentQuality]` lookup and `1000 / targetFPS` division to module-level variables. - Updated `applyQuality()` to initialize these variables. - Simplified `animate` hot path to directly use the cached configuration. - Saves CPU cycles per frame by avoiding redundant dictionary lookups and floating-point math in the hot path. - Updated `.jules/bolt.md` with new learning on render loop arithmetic overhead.

💡 What: Moved the
QUALITY_PRESETS[currentQuality]dictionary lookup and the1000 / targetFPSfloating-point division out of the high-frequencyrequestAnimationFramerender loop.🎯 Why: Performing object lookups and division every frame (up to 60+ times per second) is computationally wasteful since these values only change when the user actively modifies the animation quality settings.
📊 Impact: Reduces JavaScript execution time per frame. Specifically eliminates one dictionary hash lookup and one floating-point division per frame. While a micro-optimization, this contributes to tighter frame pacing and lower CPU/battery usage over time.
🔬 Measurement: The tests continue to pass and
currentFrameDurationaccurately throttles frames. The optimization is documented as a critical learning in.jules/bolt.md.PR created automatically by Jules for task 2697838671991070173 started by @raythurman2386
