To reach a wide audience, 3D F2P games must be playable on low-end PCs. And to successfully compete in the worldwide marketplace, games' visual and simulation fidelity must also exceed players. expectations on high-end PCs. What is the best way to create an experience that best serves both extremes? It is important to first accurately identify your game.s core mechanics. Then, determine how they will be realized on the minimum specification computer. The next step is to decide which methods will be used to enhance your game's user experience. The production ramifications of using each level-of-detail (LOD) technique must be considered to finish your scalable high-quality game on time and within budget. We will first introduce various LOD related concepts and then cover some of the common misconceptions made when determining core mechanics. Finally, the majority of session will be devoted to specific LOD approaches for rendering, animation, simulation, and visual effects. For each technique, we will provide an overview, performance benefits, methods to improve the results, and detail the production and scheduling requirements.
