It looks prettier, but when you're traveling through a system, it feels as though the whole system is a gravity well! It's like flying through molasses. It does seem a little easier to slowdown and brake.
I also think my ship moves differently with fa off, than it used to, ive had much better success controling it than i used to.
Boosting gives a greater and longer benefit to manoeuvrability than it used to, depending on pip assignment. This has a significant effect on all ships, but it's really noticeable on the FdL and the Viper Mk. III. It's less in-your-face in bigger ships like the Python, but it's still definitely there. 4 pips to ENG FA-off in a Vulture is like riding a bucking bronco. It's great!
It's in the patch notes.
