Looks comes second to me. I care more about FPS stability than fancy graphics, so I'm willing to sacrifice if higher settings are awfully laggy to the point where it's unplayable. NXT is apparently much better at managing and using your hardware though, so it should be a big step up and some may even be able to play with better frame rates.
Sometimes low detail can be useful for skilling, especially if you want to easily remember where to stand at specific spots for things like Hunter (as you can see the tiles on the ground).
Problem with my system is I have a relatively weak CPU (AMD Athlon x4 860k) and considering how the current client is heavily CPU-bound, I get lag issues in some places (especially combat) but it's manageable thankfully. NXT won't be so CPU-bound and will start using more of your GPU, which is something we definitely need. Plus, it'll be able to use more cores if your CPU has multiple cores, so that's even better!
Unless you're running on an extremely old PC with like 512MB RAM, a single-core CPU with low clock speeds and some slow-ass hard drive, you shouldn't have too many problems tbh.
