 If you have any other post-processing effects on your camera that make use of the `OnPreCull` method, then also add the `Fsr3UpscalerImageEffectHelper` script to the camera and move it up, above those other post-processing effects.

Unity's `PostProcessLayer` script is a particularly good example of this.
