Upscaling with SD 1.5 LCM LoRa have some advantages, speed is the obvious one, this is ~2x faster than my last uploaded SDXL Turbo workflow. But this workflow also is great at finer details, realistic landscapes and sharp illustrations.

I tried to explain every configuration with notes inside the workflow but is possible that I missed something, feel free to ask and in the comment and I'll answer when I see it.

Denoise is really sensitive so even at 0.20 it works, the range I recommend is 0.20 ~ 0.55.
