Have you invistigated using AI to upscale all your graphics and textures. It should be possible and almost free compared to having a person do it. I’d be interested in seeing what the tech behind DALL·E 2 could do but instead of prompting the AI with a text description, you feed it your current textures and models.
Anyway, thank you for this great and affordable game! Having a lot of fun playing.
You might be interested to know that DLSS uses machine learning to do upscaling. Unfortunately, I understand the 2019 version of Unity Last Epoch uses doesn’t support DLSS, but if they upgrade to Unity 2021 (big job mind you), they get native support for it
