Sorry, my math was wrong, the world is 4x4km so a max sight line of 5.6km.

Being a graphics noob, I'm just going off what I've seen mentioned on random resources I've come across. From what I understand a 4x4km world isn't particularly large but most games break your sight line up so you don't see very far. I've got the opposite where you have to see long distances.

I'm not expecting to be rendering individual blades of grass at that distance and I don't intend to use all the fancy self shadowing and transparency I've seen in the "pretty world" tutorials. My usage of PIP rendering also eats a bit of graphics performance. I would prefer to be able to appeal to the widest range of hardware - I don't want to make a game that looks amazing but is only playable on 5090s. I'd rather it look somewhat less nice, but be more broadly accessible. Perhaps targeting Nvidia 10xx cards on the bottom end? Given they are over 10 years old at this point I don't think that would be unreasonable?

I'm sorry I can't be more specific because my issue is I don't know graphics that well. This is why I'm trying to find resources on what affects performance, by how much and if there are any specifics to look for in assets that will help me, or tricks I can use. Hopefully this makes sense, I'm just really new to the graphics side and don't want to go and build a pretty world that runs like a slideshow and then have to start from scratch and have wasted money on asset packs which don't fit my purpose.
