# Tiled Sampling Example
|
||
|
|
|
||
|
|
Uses blenderneko's [Tiled KSampler node](https://github.com/BlenderNeko/ComfyUI_TiledKSampler)
|

|
|
## Purpose
|
||
|
|
|
||
|
|
This workflow uses tiled sampling to sample large images in hirez fixes. The Tiled KSampler is similar to the Advanced KSampler node, so there's a couple imporant differences from the "standard" KSampler.
|
||
|
|
* denoise is handled through start and stop steps compared to total steps.
|
||
|
|
* using 30 steps, start at step 15 and end at step 30 (15 steps) is equivalent to 0.500 denoise.
|
||
|
|
* Tile Width and Height should be the maximum size the GPU can reasonably handle.
|
||
|
|
* setting these values low can result in extra artiftacts and noise
