What should this feature add?

Please allow user to set the tile size for the tiled upscaling. Current hardware allows for much higher tile size than 1024x1024, and the amount of tiles drastically influences the quality of the final output. It could be set once somewhere in the settings for instance, because usually the less tiles the better, and the only limiting factor is a VRAM amount, which don't change. So it could be set once, and used by default always, just like it's now set to 1024.

Alternatives

Could be a slider with the numeric text field, or a dropdown.
