Talking aqbout passengers, it's obvious somebody is putting a lot of time into the cosmetic side of things. There is now a vast variety of clothing, different postures, NPCs conversing, people on bikes, suitcases and phones- somebody has put a lot of work in. But the underlying passenger AI remains where it was in TSW 2/RH. Frankly, it needs to be reworked from the ground up, assigning each little NPC a goal from spawn so that he/she will behave in a rational fashion, like a traveller going from point A to point B via train. Currently they are programmed like a zombie horde, and that's how they behave.
Nail. Head. Blurry textures are a built-in UE mechanism, to reduce LOD when VRAM gets overloaded. Consoles and weaker PCs don't have enough VRAM to handle the more complex routes.
I would suggest the consoles do, or would, have enough VRAM if memory was managed optimally like many other complex games with highly detailed assets on consoles. It's possible that it's not automatically scaling assets the way it should, too, such as trying to force-feed 4K assets through the pipeline.
Keeping them off the track would be a good start. Scarred for life with the amount of fatalities I have to deal with on a daily basis!
