Optimizing rendering performance
As we continue adding more objects into a game scene, we will inevitably face significant rendering performance issues. Performance is an unavoidable challenge in game development, and the key lies in analyzing the primary causes of slowdowns and applying effective strategies to address them.
In the game industry, profiling tools (such as RenderDoc or Pix) are commonly used to identify performance bottlenecks in the code. However, you don’t always need to rely on such specialized tools. Sometimes simply inserting timing measurements directly into your program, or even adjusting the number of objects being rendered, can provide enough insight to perform effective optimizations.
In this section, we’ll walk through an example of how to approach optimization in a game project.
Let’s recall the BonusGameWorld01 project, where we placed 600 decorative objects in the scene—far more than the earlier sample codes that...
