  2. To improve the quality of textures and materials

  3. To optimize the game's memory usage

  4. To increase the game's frame rate
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mesh Instancing reduces the number of draw calls in a scene by rendering multiple instances of the same mesh with a single draw call, thereby improving performance.

Multiple choice

What is the purpose of Texture Atlasing in Game Engine Optimization?

  1. To reduce the number of texture fetches in a scene

  2. To improve the quality of textures and materials

  3. To optimize the game's memory usage

  4. To increase the game's frame rate
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Texture Atlasing reduces the number of texture fetches in a scene by combining multiple textures into a single texture atlas, improving performance by reducing the number of texture switches.
