There's a simple solution. Model and texture that station so it looks as good as the one in WCS but is more efficient. In the mean time, the current one seems to work just fine without FPS drops for me. It's tempting to say things like that, but speaking as someone who's fully modeled and textured quite a bit of stuff, when you see someone doing something as enormous you might want to cut them some slack, especially if it works in the end. Getting huge stuff just looking right (let alone working right) in the game is a whole different ball game to pretty much anything else. You want it to look good while you're still reasonably close, and you want it to be nice and detailed. And it's huge. Sorry, that's going to cost. Sure you can optimize and save here and there by smart planning, tiling where applicable, etc, but in the end anything that huge will be a resource hog if you want it looking right. If it works on most current systems without issues, it's probably best to count your blessings and leave it.
