Rendering Debugger window reference

The Rendering Debugger separates debug items into the following sections:

• Decals
• Display Stats
• Material
• Lighting
• Volume
• Rendering
• Probe Volume
• Camera
• Virtual Texturing

Refer to Use the Rendering debugger for more information.

Decals panel

The Decals panel has tools that you can use to debug decals affecting transparent objects in your project.

Debug Option	Description
Display Atlas	Enable the checkbox to display the decal atlas for a Camera in the top left of that Camera's view.
Mip Level	Use the slider to select the mip level for the decal atlas. The higher the mip level, the blurrier the decal atlas.

Display Stats panel

The display stats panel is only visible in play mode. You can use it to debug performance issues in your project.

Use the [runtime shortcuts](#Navigation at runtime) to open the Display stats window in the scene view at runtime.

Frame Stats

The Frame Stats section displays the average, minimum, and maximum value of each property. HDRP calculates each Frame Stat value over the 30 most recent frames.

Property		Description
Frame Rate		The frame rate (in frames per second) for the current camera view.
Frame Time		The total frame time for the current camera view.
CPU Main Thread Frame		The total time (in milliseconds) between the start of the frame and the time when the Main Thread finished the job.
CPU Render Thread Frame		The time (in milliseconds) between the start of the work on the Render Thread and the time Unity waits to render the present frame (Gfx.PresentFrame).
CPU Present Wait		The time (in milliseconds) that the CPU spent waiting for Unity to render the present frame (Gfx.PresentFrame) during the last frame.
GPU Frame		The amount of time (in milliseconds) the GPU takes to render a given frame.
RT Mode		When you enable ray tracing, this property shows the ray tracing quality mode that HDRP uses during rendering. HDRP updates this value once every frame based on the previous frame.
Count Rays		Count the number of traced rays for each effect (in MRays / frame). This property only appears when you enable ray tracing.
	Ambient Occlusion	The number of rays that HDRP traced for Ambient Occlusion (AO) computations, when you enable realtime ambient occlusion (RT AO).
	Shadows Directional	The number of rays that HDRP traced for directional lights when you enable ray-traced shadows.
	Shadows Area	The number of rays that HDRP traced towards area lights when you enable ray-traced shadows.
	Shadows Point/Spot	The number of rays that HDRP traced towards point and spot lights when you enable ray-traced shadows.
	Reflection Forward	The number of rays that HDRP traced for reflection computations that use forward shading.
	Reflection Deferred	The number of rays that HDRP traced for reflection computations that use deferred shading.
	Diffuse GI Forward	The number of rays that HDRP traced for diffuse Global Illumination (GI) computations that use forward shading.
	Diffuse GI Deferred	The number of rays that HDRP traced for diffuse Global Illumination (GI) computations that use deferred shading.
	Recursive	The number of rays that HDRP traced for diffuse Global Illumination (GI) computations when you enable recursive ray tracing.
	Total	The total number of rays that HDRP traced.
Debug XR Layout		Display debug information for XR passes. This mode is only available in editor and development builds.

Bottlenecks

A bottleneck is a condition that occurs when one process performs significantly slower than other components, and other components depend on it.

To display the current active item independently of the debug window:

Note: Vsync limits the Frame Rate based on the refresh rate of your device’s screen. This means when you enable Vsync, the Present Limited category is 100% in most cases. To turn Vsync off, go to Edit > Project settings > Quality > Current Active Quality Level and set the Vsync Count set to Don't Sync.

Bottleneck categories

Category	Description
CPU	The percentage of the last 60 frames in which the CPU limited the frame time.
GPU	The percentage of the last 60 frames in which the GPU limited the frame time.
Present limited	The percentage of the last 60 frames in which the frame time was limited by the following presentation constraints: • Vertical Sync (Vsync): Vsync synchronizes rendering to the refresh rate of your display. •Target framerate: A function that you can use to manually limit the frame rate of an application. If a frame is ready before the time you specify in targetFrameRate, Unity waits before presenting the frame.
Balanced	This percentage of the last 60 frames in which the frame time was not limited by any of the above categories. A frame that is 100% balanced indicates the processing time for both CPU and GPU is approximately equal.

Bottleneck example

If Vsync limited 20 of the 60 most recent frames, the Bottleneck section might appear as follows:

• CPU 0.0%: This indicates that HDRP did not render any of the last 60 frames on the CPU.
• GPU 66.6%: This indicates that the GPU limited 66.6% of the 60 most recent frames rendered by HDRP.
• Present Limited 33.3%: This indicates that presentation constraints (Vsync or the target framerate) limited 33.3% of the last 60 frames.
• Balanced 0.0%: This indicates that in the last 60 frames, there were 0 frames where the CPU processing time and GPU processing time were the same.

In this example, the bottleneck is the GPU.

Detailed Stats

The Detailed Stats section displays the amount of time in milliseconds that each rendering step takes on the CPU and GPU. HDRP updates these values once every frame based on the previous frame.

Property	Description
Update every second with average	Calculate average values over one second and update every second.
Hide empty scopes	Hide profiling scopes that use 0.00ms of processing time on the CPU and GPU.
Count Rays	Count the number of traced rays for each effect (in MRays / frame). This mode only appears when you enable ray tracing.
Debug XR Layout	Enable to display debug information for XR passes. This mode only appears in the editor and development builds.

	Quad Overdraw	Select this option to display an overlay that highlights gpu quads running multiple fragment shaders. This is mainly caused by small or thin triangles. Use LODs to reduce the amount of overdraw when objects are far away. (This mode is currently not supported on Metal and PS4).
	Vertex Density	Select this option to display an overlay that highlights pixels running multiple vertex shaders. A vertex can be run multiple times when part of different triangles. This helps finding models that need LODs. (This mode is currently not supported on Metal).
	TransparencyOverdraw	Select this option to view the number of transparent pixels that draw over one another. This represents the amount of on-screen overlapping of transparent pixel. This is useful to see the amount of pixel overdraw for transparent GameObjects from different points of view in the Scene. This debug option displays each pixel as a heat map going from black (which represents no transparent pixels) through blue to red (at which there are Max Pixel Cost number of transparent pixels).
	RequestedVirtualTextureTiles	Select this option to display what texture tile each pixel uses. Pixels that this debug view renders with the same color request the same texture tile to be streamed into video memory by the streaming virtual texturing system. This debug view is useful to see which areas of the screen use textures that the virtual texturing system steams into video memory. It can help to identify issues with the virtual texture streaming system.
	LensFlareScreenSpace	Display the lens flares that the Screen Space Lens Flare override generates.
	Compute Thickness	Select this option to display thickness for each layer selected in the current HDRP Asset and configure the following properties: • Layer Mask: Set the layer number to visualize in the debug view. • Show Overlap Count: Highlight the triangles that intersect for each pixel. • Thickness Scale: Set the range (in meters) of the ComputeThickness debug view. When you enable Show Overlap Count, this setting affects the Overlap Count debug view. For more information on how to debug compute thickness, refer to Sample and use material thickness.
	Max Pixel Cost	The scale of the transparency overdraw heat map. For example, a value of 10 displays a red pixel if 10 transparent pixels overlap. Any number of overdraw above this value also displays as red. This property only appears if you set Fullscreen Debug Mode to TransparencyOverdraw.
	High Quality Lines	Select this option to view underlying data used by tile-based software rasterizer for the High Quality Line Rendering feature. Segments per Tile displays a heatmap representing the number of segments in each tile. Tile Processor UV displays the uv coordinate for each tile. Cluster Depth displays segments based on their depth in the cluster structure that's used for transparent sorting.
MipMaps	Use the drop-down to select a mipmap streaming property to debug.
	None	Select this option to disable this debug feature.
	MipRatio	Select this option to display a heat map of pixel to texel ratio. A blue tint represents areas with too little Texture detail (the Texture is too small). A bed tint represents areas with too much Texture detail (the Texture is too large for the screen area). If the debugger displays the original color for a pixel, this means that the level of detail is just right.
	MipCount	Select this option to display mip count as grayscale from black to white as the number of mips increases (for up to 14 mips, or 16K size). Red inidates Textures with more than 14 mips. Magenta indicates Textures with 0 mips or that the Shader doesn't support mip count.
	MipCountReduction	Select this option to display the difference between the current mip count and the original mip count as a green scale. A brighter green represents a larger reduction (that mip streaming saves more Texture memory). Magenta means that the debugger doesn't know the original mip count.
	StreamingMipBudget	Select this option to display the mip status due to streaming budget. Green means that streaming Textures saves some memory. Red means that mip levels are lower than is optimal, due to full Texture memory budget. White means that streaming Textures saves no memory.
	StreamingMip	Select this option to display the same information as StreamingMipBudget, but to apply the colors to the original Textures.
	Terrain Texture	Use the drop-down to select the terrain Texture to debug the mipmap for. This property only appears when you select an option other than None from the MipMaps drop-down.

Color Picker	Description
Debug Mode	Use the drop-down to select the format of the color picker display.
Font Color	Use the color picker to select a color for the font that the Color Picker uses for its display.

The Color Picker works with whichever debug mode HDRP displays at the time. This means that you can see the values of various components of the rendering like Albedo or Diffuse Lighting. By default, this displays the value of the main High Dynamic Range (HDR) color buffer.

Debug Option	Description
False Color Mode	Enable the checkbox to define intensity ranges that the debugger uses to display a color temperature gradient for the current frame. The color temperature gradient goes from blue, to green, to yellow, to red.
	Range Threshold 0	Set the first split for the intensity range. This property only appears when you enable the False Color Mode checkbox.
	Range Threshold 1	Set the second split for the intensity range. This property only appears when you enable the False Color Mode checkbox.
	Range Threshold 2	Set the third split for the intensity range. This property only appears when you enable the False Color Mode checkbox.
	Range Threshold 3	Set the final split for the intensity range. This property only appears when you enable the False Color Mode checkbox.
MSAA Samples	Use the drop-down to select the number of samples the debugger uses for MSAA.
Freeze Camera for Culling	Use the drop-down to select a Camera to freeze to check its culling. To check if the Camera's culling works correctly, freeze the Camera and move occluders around it.

The Color monitors are a set of industry-standard monitors to help artists control the overall look and exposure of a scene.

Debug Option	Description
Waveform	Displays the full range of luma (brightness) information in the Camera’s output. The horizontal axis of the graph corresponds to the render (from left to right) and the vertical axis indicates the brightness value.
Exposure	Determines the exposure multiplier HDRP applies to the waveform values. This property only appears when you enable the Waveform checkbox.
Parade mode	Splits the image into red, green and blue separately. You can use this to visualise the RGB balance of the Camera's image. This helps you to see large offsets in one particular channel, or to determine if GameObjects are true black or true white. A true black, white, or grey GameObject has equal values across all channels. This property only appears when you enable the Waveform checkbox.
Vectorscope	The Vectorscope monitor measures the overall range of hue and saturation within the Camera’s image in real-time. To display the data, it uses a scatter graph relative to the center of the Vectorscope. The Vectorscope measures hue values between yellow, red, magenta, blue, cyan and green. The center of the Vectorscope represents absolute zero saturation and the edges represent the highest level of saturation. To determine the hues in your scene and their saturation, look at the distribution of the Vectorscope’s scatter graph. To identify whether there is a color imbalance in the image, look at how close the middle of the Vectorscope graph is to the absolute center. If the Vectorscope graph is off-center, this indicates that there is a color cast (tint) in the image.
Exposure	Determines the exposure multiplier HDRP applies to the vectorscope values. This property only appears when you enable the Vectorscope checkbox.
Size	The size ratio of the color monitors.

Debug Option	Description
Clear Render Targets at creation	Enable the checkbox to make the Render Graph system clear render targets the first time it uses them

Output resolution	Displays the target resolution for this particular DLSS view.
Quality	Displays the quality selected for this particular DLSS view.

Camera panels

In the Rendering Debugger, each active Camera in the Scene has its own debug window. Use the Camera's debug window to temporarily change that Camera's Frame Settings without altering the Camera data in the Scene. The Camera window helps you to understand why a specific feature doesn't work correctly. You can access all the information that HDRP uses the render the Camera you select.

Note: The Camera debug window is only available for Cameras, not Reflection Probes.

The following columns are available for each Frame Setting:

Column	Description
Debug	Displays Frame Setting values you can modify for the selected Camera. You can use these to temporarily alter the Camera’s Frame Settings for debugging purposes. You can't enable Frame Setting features that your HDRP Asset doesn't support.
Sanitized	Displays the Frame Setting values that the selected Camera uses after Unity checks to see if your HDRP Asset supports them.
Overridden	Displays the Frame Setting values that the selected Camera overrides. If you don't check the Custom Frame Settings checkbox, check it and don't override any settings, this column is identical to the Default column.
Default	Displays the default Frame Setting values in your current HDRP Asset.

Unity processes Sanitized, Overridden, and Default in a specific order:

1. It checks the Default Frame Settings
2. It checks the selected Camera’s Overridden Frame Settings.
3. It checks whether the HDRP Asset supports the selected Camera’s Frame Settings
4. It displays that result in the Sanitized column.

Interpreting the Camera window

• In the image above, Ray Tracing is disabled at the Sanitized step, but enabled at the Default and Overridden steps. This means that, although Ray Tracing is enabled in the Frame Settings this Camera uses, it's not enabled in the HDRP Asset’s Render Pipeline Supported Features.
• Also in the image above, Decals is disabled at the Overridden step, but enabled at the Default step. This means that Decals is enabled in the default Camera Frame Settings but disabled for that specific Camera’s Custom Frame Settings.

Virtual Texturing panel

You can use the Virtual Texturing panel to visualize Streaming Virtual Texturing.

Debug Option	Description
Debug disable Feedback Streaming	Deactivate Streaming Virtual Texturing to quickly assess its cost in performance and memory at runtime.
Textures with Preloaded Mips	Display the total number of virtual textures Unity has loaded into the scene. Unity tries to preload the least detailed mipmap level (least being 128x128) into GPU memory. This number increases every time a material is loaded.
