Unity Debug

Here are several tools under the IDE for debugging the CPU and GPU.

Memory profiler

When to use Memory profiler?

• Monitors real-time memory usage for both managed and native memory.
• Identifies memory allocations and leaks to optimize RAM usage.
• Tracks memory allocation per object type, helping pinpoint areas of high memory consumption.

Profiler:

When to use Profiler?

• Tracks CPU and GPU performance in terms of time spent on different tasks.
• Provides a breakdown of scripts, rendering, physics, and other processes.
• Identifies bottlenecks by showing frame time and resource usage.

Frame Debugger:

When to use Frame Debugger?

• Allows you to step through frames to visualize each draw call.
• Helps understand the order of operations in the rendering pipeline.
• Useful for debugging overdraw, incorrect rendering order, and other rendering issues.

Rendering Debugger:

When to use Rendering Debugger?

• Focuses on specific stages of the GPU pipeline.
• Helps debug shader issues, pipeline state, and resource binding.
• Useful for troubleshooting rendering artifacts or GPU-related bugs.

Rendering Graph Viewer:

When to use Rendering Graph Viewer?

• Visualizes the rendering pipeline nodes.
• Shows how resources like textures, buffers, and shaders are used in each stage.
• Helps optimize resource allocation and GPU performance.
