After testing the jump drive, I can add to what's been said that more modules takes less time to charge up, and there is a minimum and if you are below that you cannot use the system. Also the range is 7 sectors, the exact distance changes depending on sector size (default sector size lets you warp ~9k, 4000 sector size allows for ~30k)
Also, warp gate destinations are now specific to the computers that each loop is linked to, so that means that you have to link the target right to the computer, and it also means that you can have more than one loop and more than one destination per station, so you could have a warp hub.
Also, be careful with that jump drive, it will not stop you from teleporting into objects (so I don't suggest jumping directly to 2 2 2) :p
For those who can't watch videos (I believe Rimmer is having this issue), here's a screenshot of the new warp animation (sorry, I tried a gif but it was too slow to catch it):
If anyone is wondering, it appears the animation is a sky-box like effect, I made a large tower on my test ship with a camera on top and failed to see any change in perspective.
Also, Mered4, the power consumption (per second while charging) is listed under the structure tab, but I can't tell you the equations involved.
It appears that shield-nerfing and block destruction from jump drives and warp gates (respectively) have yet to be implemented as of the aug 27th build.
Last thing (hopefully): Does anyone else disagree about the .1 ratio required? Making 1/10 of your ship dedicated only to jump drive seems pretty heavy, especially when I left a decent space in my new cruiser for ftl, but I literally had to gut the thing (1/2 shields gone, 1/2 recharge gone, 1/3 weapons gone) to fit in the necessary jump drive modules. I won't complain about power usage (for the cruiser, it's 1.2*10^10 per second, drains the 3.5 mil storage in 3 seconds) but the min blocks required to use the system at all is really high (I'd probably like .05 ratio at most as the min, but ideally would want there to be a very very tiny min but it takes an insanely long time to charge, almost making it not worth jumping at all).
