UltraRes lets you render at higher resolutions than SDXL would normally allow. It supports txt2img as well as upscaling images in img2img to bigger image sizes than previously possible. Without the lora distortions occur at these resolutions.

The lora supports rendering up to 3 megapixel in txt2img and up to 7 megapixel in img2img. It was trained on Big Love XL2.5 with 130 images from the training sets of Subtle Styles and Sublte Poses. It is recommended to use it with Big Love XL2.5 and the DMD2 lora. For settings check the Big Love description.

Supported txt2img Sizes:
1536x2048, 1344x2016, 1280x1920, 1248x1824, 1536x1536 (and their landscape versions)

img2img Upscale Factor:
1.5 or 1.25

Recommended Lora Strength:
0.5 to 1.0: The higher the resolution, the higher the lora strength has to be to avoid distortions. Higher lora strength means less sharp details, so keep it as low as possible and as high as necessary.
