X-Frame FPS Accelerator · Core Concepts

Settings Reference

All settings are available on the XFrameManager component attached to your camera.

General Settings

Property	Description
Method	Downsampling algorithm: `Horizontal Downsampling`, `Quad Downsampling`, or `Adaptive Downsampling`. When URP is used, Adaptive Downsampling is always used internally.
Minimum FPS	Target frame rate. X-Frame only activates when FPS drops below this value.
Preserve Nice FPS	If FPS exceeds this threshold, X-Frame is temporarily disabled to avoid any overhead.
Show FPS	Display the FPS counter and optionally the current quality level (percentage where 100% = full resolution).

Quality Management

Property	Description
Adapt Speed Up	Speed of quality increase when FPS is above target. Higher values = faster quality recovery.
Adapt Speed Down	Speed of quality decrease when FPS is below target.
Minimum Quality	Lowest allowed resolution factor (0.1–1.0). Controls the maximum performance gain vs. image quality trade-off.
Static Camera Quality	Resolution factor used when the camera is stationary. Can be higher than Minimum Quality for better visuals during idle moments.
Reduce Pixel Count	Reduces pixel light count down to 1 if the target FPS is not met. The Threshold setting controls the minimum resolution before this activates.
Manage Shadows	Automatically adjusts shadow quality per light (soft → hard → disabled) based on current FPS.
Manage LOD Bias	Adjusts the global LOD bias to switch to higher LOD levels earlier, reducing triangle count.

Rendering Settings

Property	Description
Filtering	Upscale filter: `Nearest Neighbour` (faster, pixelated) or `Bilinear` (smoother, slight blur).
Antialias	MSAA level for the off-screen render. Values of 2+ dramatically improve quality. Independent of project MSAA settings.
Clear Flags	Clear mode for the X-Frame camera. Set to `Solid Color` if you see ghosting artifacts.
Blend with Background	When enabled, X-Frame does not clear the background, allowing layered camera setups.
Render Method	`Second Camera Billboard World Space` (default, recommended) or `Second Camera Blit` (slower on older devices but supports sharpening).
Sharpen Image	Apply a sharpening pass during upscale. Only available with the Blit render method.
Prewarm	Pre-allocate render buffers at startup to avoid hitches when resolution changes.
GameObject Clicks	Enable raycasting and bubbling of `OnMouseDown`, `OnMouseUp`, `OnPointerClick` events through X-Frame.
Boost Frame Rate	Sets Unity's target frame rate and VSync to optimal values for maximum FPS.
