Good for quick 4k wallpaper generation.

Ultimate SD Upscale with SDXL Lightning is much faster, but can cause issues like glitches or style changes.

Is it possible to unload the models before loading the next one? The system crashes due to RAM overload when attempting to load the SD model for upscaling, which I believe is the cause.
Hi, I don't run into that issue. Flux fills the vram of my 4080 and 32gb of ram completely up, while generating and upscaling, but my system keeps running. I may be wrong, but I don't think, Flux is still loaded, when Ultimate SD Upscale starts. Observing my sensor panel, memory gets partially flushed, before.
You could try, cutting the Ultimate SD Upscale part out of the workflow and run it separately as img2img, to see, if it works then.
@Crysis1987 very weird since I also have a 3090 and 32gb of ram so it should technically work for me too. With other workflows I didn't have this issue.
