This extension integrates AMD FidelityFX Super Resolution (FSR) 1.0 upscaling feature into stable-diffusion-webui. AMD FSR1 is based on Lanczos upscale, so don't expect anything amazing. You can use it inside hires fix, upscaler_for_img2img or in the extras tab.
Extension will automatically download the FidelityFX_CLI executable during the first run. No manual setup is required. For linux you need to have wine in PATH
This extension offers FSR 1.0 Contrast Adaptive Sharpening upscaling at 2x, 3x, and 4x scales, as well as in a universal mode that is tied to the scale you set in hiresfix.
This extension is primarily designed for Windows. For linux you need to have wine in PATH
Please note that while this integration allows you to use FSR 1.0 within the stable-diffusion-webui environment, there are also other high-quality upscaling options available. Special thanks to light-and-ray, it was his extension with Topaz Photo AI integration as an upscaler for stable diffusion that inspired me to do the AMD FSR integration, so I suggest you check it out Topaz Photo AI integration.
