  2. Level of Detail (LOD) Management

  3. Occlusion Culling

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Dynamic Resolution Scaling, Level of Detail Management, and Occlusion Culling are all widely used techniques for optimizing graphics performance in games by adjusting resolution, reducing the complexity of distant objects, and selectively rendering visible objects, respectively.

Multiple choice

Which of the following is a common technique used for optimizing memory usage in games?

  1. Texture Atlasing

  2. Mesh Instancing

  3. Dynamic Memory Allocation

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Texture Atlasing, Mesh Instancing, and Dynamic Memory Allocation are all widely used techniques for optimizing memory usage in games by reducing texture fragmentation, reusing meshes, and efficiently managing memory resources.

Multiple choice

Which of the following is NOT a common approach for optimizing shader performance in games?

  1. Using a high-level shader language

  2. Optimizing shader code for specific hardware

  3. Using pre-compiled shaders

  4. Using a shader compiler with advanced optimization features
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

While optimizing shader code, using pre-compiled shaders, and using a shader compiler with advanced optimization features are common approaches for optimizing shader performance, using a high-level shader language is not directly related to game engine optimization.
