>>2757488It depends on what you've been doing
Did you use highres fix? Either change your upscaler to something like R-Ersgan 4x+ Anime6B or set your denoise to 0.5-0.6 if you haven't
Did you use Ultimate SD Upscaler extension? Hit me with your setting and we can work from there
Did you not use either of those and just set your resolution that high from the beginning? Well, stop doing that and pick one of the above method
