yeah. probably.
but these are open source projects. so they have to do everything on their own. we paid someone who should have created a tool or environment that allowed us to achieve something similar without having to do what these open source guys do enginewise.
on the other hand, looking from the art side, you are right. even if conitec had that level of hq shadow mapping and shading inside 3dgs, the typical 3dgs screenshot would still show warlock models, cubes, and ms paint textures.
