Settings

Maximum tile WxH

Max Tile Resolution = TileWidth x TileHeight

To find out max tile resolution your VRAM can handle you need to experiment (you can use "Create max resolution tile in LR" setting for this). Default value is for ~2GB of VRAM.

Tiles overlap

When creating tiles, they will be overlapping between themselves by size in pixels specified by this value. The bigger value - more time to process tiles with ESRGAN. Improvement from setting this bigger than 16 is questionable.

Output format

Image format in which images will be written to disk on merge. If you check "Use original image format", output format will be the same as original image, but some setting (like compression factor, method) will be taken from Output format tab.

Ignore alpha channel

If checked, all alpha channels will be ignored during tiles creation and merge.

Use different model for alpha

If checked, selected model will be applied to all alphas when running ESRGAN. Alpha tiles will be saved to /LR_alpha folder.

Split RGB channels

If checked, images will be split into red, green and blue channels and ESRGAN will process each channel as separate image. Channels will be combined back in single image on merge, if this setting is enabled.

Split RGB channels

If checked, will treat all images as tiles textures and extend them over edges on Split and crop them back on Merge. This way textures will remain seamless after upscale.

Create max resolution tile in input folder

Creates blank black image with max TileWith and TileHeight. It's might be needed because if ESRGAN starts with small image and then tries to process bigger image it can run in out of memory error.

Delete results after merging

Deletes all of merged tiles in result folder after successfully merging image .

Use suffix

Useful when you are using tool other than ESRGAN and your processed image results have some suffix. Just check this option and write suffix in textbox before merging tiles.
