## TL;DR

Game performance optimization starts with measurement, frame budgets, and bottleneck isolation rather than guesswork.

## Core Explanation

Good optimization keeps the player experience in view: stable frame times, responsive input, and target-hardware profiling matter more than isolated micro-optimizations.
