Open DevTools > Performance, record while the game runs, then read the flame chart for long tasks, scripting vs rendering vs painting time, and dropped frames. Fix the largest bar first, re-record, and repeat. Use Memory and Rendering panels for leaks and paint issues.<\/strong><\/p>\n

Open DevTools, go to the Performance<\/b> panel, click record, play the part of the game that feels slow, then stop. The flame chart underneath the frame timeline shows main-thread work broken into Scripting (yellow), Rendering (purple) and Painting (green). Click into a long task and follow the call stack down to the function actually eating time – that’s your bottleneck, not the frame that just happened to be slow.<\/p>\n

Look at the Summary tab for the split between scripting, rendering, painting and idle time, and watch the FPS chart for red bars (dropped frames). If scripting dominates, check your update\/tick loop and any per-frame allocations; if rendering\/painting dominates, check canvas size, layer count and CSS that triggers layout. The Memory<\/b> panel (heap snapshot, allocation timeline) catches leaks – a heap that keeps climbing across repeated play sessions without dropping means objects aren’t being released. The Rendering<\/b> tab (paint flashing, layer borders) shows exactly what repaints on each frame.<\/p>\n

What order should I check things in?<\/h2>\n
