Performance optimization Performance work is a measurement discipline, not a bag of tricks. The method is always the same: profile → find the one bottleneck → fix that → measure again . This skill teaches that loop and the highest-leverage fixes (pooling, batching, allocation control, asset budgets), and points you at each engine's profiler. It pairs with for simulation cost. When to use - Use when the frame rate is low or uneven, the game stutters/hitches, or it must hit a target (60 FPS desktop, 30/60 mobile) and currently doesn't. - Use to decide what to optimize: profile, read the frame b…
