Quality Tiers & PerformanceSettings

The ScriptableObject

PerformanceSettings is the central configuration asset. It contains:

Tiers - an ordered list of QualityTier (index 0 = highest quality).
Dynamic Performance - settings for the automatic FPS monitor.
Persistence - save file name for player preferences.

QualityTier Fields

Each tier controls the following parameters:

Pipeline & Performance

Field	Type	Default	Description
`tierName`	string	"Medium"	Display name for this tier
`renderPipelineAsset`	RPA	null	Optional: swap the entire pipeline asset
`renderScale`	float	1.0	Internal render scale (0.1 – 2.0)
`lodBias`	float	1.0	LOD distance multiplier
`vSyncCount`	int	1	0=Off, 1=60Hz, 2=30Hz
`targetFrameRate`	int	-1	-1 = unlimited

Shadows

Field	Type	Default	Description
`shadowDistance`	float	150	Maximum shadow distance
`shadowCascades`	int	4	0, 1, 2, or 4 cascades
`shadowResolution`	enum	High	Low / Medium / High / VeryHigh
`softShadows`	bool	true	Soft shadow edges

Textures & Streaming

Field	Type	Default	Description
`globalTextureMipMapLimit`	int	0	0=Full, 1=Half, 2=Quarter
`textureStreamingBudget`	int	4096	Budget in MB. Set to 0 to use Global Settings.
`anisotropicFiltering`	enum	Enable	Disable / Enable / ForceEnable
`realtimeReflectionProbes`	bool	true	Realtime reflection probes
`softParticles`	bool	true	Soft Particles (Fades near geometry)

Post-Processing

Field	Type	Default	Description
`enableBloom`	bool	true	Toggle Bloom
`enableAO`	bool	true	Ambient Occlusion
`enableDepthOfField`	bool	false	Depth of Field
`enableMotionBlur`	bool	false	Motion Blur
`enableChromaticAberration`	bool	false	Chromatic Aberration
`enableVignette`	bool	false	Vignette
`enableTonemapping`	bool	true	Tonemapping / Color Grading
`enableSSR`	bool	false	Screen Space Reflections
`enableLensDistortion`	bool	false	Lens Distortion
`enableSSGI`	bool	false	Screen Space GI
`enableVolumetricClouds`	bool	false	Volumetric Clouds

URP-Specific

Field	Type	Default	Description
`mainLightShadows`	bool	true	Main light shadows
`msaaLevel`	enum	4x	Off / 2x / 4x / 8x
`enableDecals`	bool	true	Toggle Decals (works for HDRP too)

Note: These fields only appear and function when URP is installed.

HDRP-Specific

Field	Type	Default	Description
`enableRayTracing`	bool	false	Global RT toggle
`rtGlobalIllumination`	enum	Off	Off / Performance / Quality
`rtReflections`	enum	Off	Off / Performance / Quality

`enableVolumetricFog`	bool	true	Volumetric fog

Note: These fields only appear and function when HDRP is installed. The RayTracingTier enum provides three modes:

Off - Ray tracing disabled for this effect.

Performance - Fewer samples/bounces, suitable for real-time games.

Quality - Maximum fidelity, higher GPU cost.

Extensions (Advanced)

Field	Type	Default	Description
`contactShadows`	bool	false	Contact Shadows (SSCS)
`grassDistance`	float	50	Terrain grass/detail draw distance
`aaMethod`	int	1	0=Off, 1=FXAA, 2=SMAA, 3=TAA
`enableVRS`	bool	false	Variable Rate Shading
