What is the primary function of the arrows found in the Frame Debugger?

The primary function of the arrows in the Frame Debugger is to sequentially move through individual draw calls. The Frame Debugger is an essential tool in Unity that allows developers to analyze how a scene is rendered by providing a visual breakdown of all draw calls made during the rendering process.

When using the arrows, users can navigate through each draw call one by one, which helps to understand the sequence in which objects are rendered on the screen. This is crucial for optimizing performance, as it allows artists and developers to identify redundant or inefficient rendering processes, such as unnecessary draw calls or other issues that could impact frame rates.

Understanding the draw call order is vital for optimizing a game’s performance. By examining draw calls sequentially, developers can make informed decisions about which objects can be combined or batched together to minimize the rendering load, ultimately improving the overall efficiency of the game.
