Upscale Shaders

Example (Original / Upscaled)

Performs super-resolution. Increases (usually double) image size with the expectation that the low resolution image is artifact-free. I.e. No noise, blur or any other degradation.

Any degradation remaining on the image will be amplified. It is better to use other shaders first to reduce noise or blur.

CNN_M and CNN_L variants also introduces small amounts of checkerboard artifacts due to the pixelshuffle layer and the low parameter count.
