I figured there is a need for generating a lot of samples and building a predictive model per game for best results. Documentation confirms:
> Most of these corner cases can be resolved by providing the model with enough training data without increase the complexity and cost of the technique. This
also enables game developers to train the neural upscalers with their
content, resulting in a completely customized solution fine-tuned for the
gameplay, performance, or art direction needs of a particular title.
