> The mutable execution parameters used by FSR2 for each frame.

## Definition

* **Type:** Property

```

### Remarks

Modify this data before invoking [GraphicsDevice.ExecuteFSR2](/engine/6000.6/script-reference/unityengine/amd/graphicsdevice/executefsr2.md) to control frame-specific behavior such as jitter, motion vector scale, sharpness, and camera properties.
