Star Citizens is not performance optimized in any any way, performance is all over the board even on very powerful computers, personally I can run the arena commander fine, at medium/high, but universe play? nope, bad performance, very low cpu and gpu usage, though it has improved with the latest 2.1 , so they are working on it.
That said, a lot of people seem to think that Star Citizen will have fully explorable planets, they won't it isn't within the scope, for scope see wing commander/freelancer, great games yes, but planetary exploration isn't part of it.
Heck Chris Roberts has even said that procedural generation is very very hard to get right, yet personally I think Elite is doing it very..very well, yes its not perfect, but the road to perfection is just that a road.
A lot of people don't seem to consider that Elite and Star Citizen started development at approximately the same time, from two different starting points and with two different models for development.
Both are great games, and being made even better, I'm likely going to play both, and last I checked there's no harm in that, I enjoy Elite a lot, and am excited for Star Citizen, and really wish people would stop pitting them against each other without understanding what is actually going on, and this isn't a jab or anything at OP. But a hope, that people will do more then "X is better then Y" "No it isn't" "yes it is" and so on, like Elite? play Elite, like Star Citizen? play Star Citizen, Like both? play both?
Enjoy the games you like to play, play them. Its fine to bring up points, but this whole thing is getting rather silly on a whole

(And yes I know, it isn't just these games that this happens with)
