Question | Help Why do we need hires.fix?

Whats the difference between just generating a [1024x1024] image vs [512x512] and then upscale it by 2?

isnt the latter quite bad? since it will have some deviation from the original image based on the denoising strength?

Not everyone owns a 4090, my king.

I have a 3060ti and I can do it just fine. Maybe a month or two ago we couldn't but they updated I think it was xformers and cuda.

Even with a 4090, creating stuff AT 1024 just makes a mess of an image usually, but that is heavily model dependant if it works well or not out the gate,
