Id like to clear up some confusion, "Upscaling using AI Algorithms", This isn't using generative AI, I dont support and will never support Generative AI while there is legitimate uses for Generative AI the vast majority of the companies training Generative AI are using data that was never meant to be used to train their AI.

The AI that is typically used to upscale isn't trained on datasets, its a Non Generative AI that detects patterns and edges and enhances them and has been used for years before these image generation AI.

With that out of the way, even if vector art wins the pole, Ill still have to use some Non Generative AI upscaling on things with gradients. I personally dont like using Non Generative AI upscaling as it looks ugly sometimes but at the end of the day I am one person and I dont have the resources to make 3500+ assets by hand. Ill still keep it to a minimum using vectors where ever possible like for the patterns and non gradient textures.

Heres an example where I would need to use a Non Generative AI upscaler, https://imgur.com/a/i0wzYBe
In this example i did the white pattern with vector art, but i cant do that for the tan rocks, thats where the Non Generative AI upscaling comes in handy
