FL Upscale Model
This node upscales the input to the size of your model so if you use a 4x model it will upscale the images to 4x, you then use the "downscale by" widget to tell it where to go down from that destination.
4x model then downscale by: 0.5 = 2x initial res
2x model then downscale by: 1 = 2x initial res
FL KSampler Plus
Start with these settings
denoise: 0.2
overlap: 0.05
steps: 4
cfg: 1 to 2
sampler_name: lcm
scheduler: beta
input type: image
Slicer settings allow you to do tiled upscaling with very clean seams. That means more tile runs at lower res quilted together into a super high res version.
slicer_x = num slices on the x axis (horizontal)
slicer_y = num slices on the y axis (vertical)
16:9 is wide so
slicer_x: 2
slicer_y : 1
9:16 is tall so
slicer_x: 1
slicer_y: 2
square tiles are square so just make the tile slices equal
Your goal is to make sure the tiles are less than 1024x1024, so if you're going to like 4k you will need more tiles.
