The below example is of a 512x512 image with hires fix applied, using a GAN upscaler (4x-UltraSharp), at a denoising strength of 0.45. The image on the right utilizes this extra noise tweak.

Note that the previous setting implemented at the time (`Noise multiplier for img2img`) technically achieves the same effect, but as noted in the name *only* applies to img2img (not hires fix), and due to how that parameter functions it is very sensitive, realisticly only useful in a range of `1` to `1.1`. For almost all operations it would be suggested to use the new `Extra noise` parameter instead.
