[Feature Request] Multi-Step Upscaling
Connum opened this issue · 1 comments
In my experience, I get better results with multi-step upscaling, e.g. running a 1.5x upscaling, then dragging the output to the input and perform another 1.5x upscaling. The result will usually be better than what a 2.25x upscaling in one step would achieve.
I would love to have the possibility to specify a list of steps that will be performed automatically and have each subsequent step re-uses the output of the previous one, similar to the loopback option.
It could even allow for a combination of factors and fixed resolutions, e.g.
1.5,1.25,2650x1440
would perform a 1.5x upscaling, followed by a 1.25x upscaling of the previous result, then upscale to the final resolution of 2650x1440.
This is a very good idea! Indeed, if I choose the 4x upscaling (4x-UltraSharp model), I get a worse result than in the case of 2x+2x.
