Simple SUPIR Upscale版本v1.2 (ID: 700888)

SDXL Lightning is loaded by default. You may have to tweak the cfg and steps for classic SDXL model.

The Supir Rescale factor is set to 1, which means that if you have a 4x upscaler model loaded, it will upscale your image by 4. Set the factor to 0.5 for a 2x upscale, (as an example.)

Be aware that the scale factor from SUPIR and StableSR are not the same, Supir should be = or above 0.5, and StableSR = or above 1.15

Also if you are using an XL lightning model, set the CFG from StableSR to 1/1.5, if not keep it as it is around 4/5, the supir CFG doesn't need to be changed
