I think the issue with exiting the ship is an unintended side effect of the game's physics engine and how it handles in-air collisions between the avatar and any object. I've seem similar behaviour when using the jet pack and accidentally being bumped by some of the local fauna.

You might try just a brief pulse on the jetpack as you exit the ship, to get you past whatever piece of superstructure you may be bumping into on a normal exit. Perhaps in combination with a turn to one side or the other?

As regards the stuttering and rubberbanding, there are probably at least twice as many recommended solutions for graphics issues as there are players. Assuming that you have already matched the game's texture mapping, anti-aliasing, and so on with your graphics card capabilities, try turning off vertical sync. That can lead to some visible "tearing" from partial screen updates but may also allow asynchronous frame rendering that looks smoother.

Or, wait around for some of the other 2 * (N -1) possible solutions. ;-)

Thanks for the helpful reply I'll see what I can do

This is a known bug for a long time now. It usually happens with Exocrafts. It happens most if your ship or vehicle is not level on the ground when you exit.

I've been thrown from the Nomad a lot. I also sometimes take damage when exiting the ship. This damage repeats at regular intervals until I use the jet pack.

I think you can do it on purpose when hitting E and almost instantly W and SPACE for the jetpack. But I don't recommend it, because you can land minutes away from your ship, and in survival you probably will die :)

Well, I've finally joined the Flying Nomad club. Was using it to gather Pt on my base's island for some ship upgrades; Pt is scarce on the island but the weather is nice. ;-)

Anyway ... I got booted six minutes away into the middle of the ocean. Not. Happy. And it turns out that summoning an exocraft doesn't work while you're treading water, so it was swim or die.

Fortunately, there's a trick (which I am probably the last to figure out) to covering distance in the water. It's not that much faster than normal swimming but it does help. Have the avatar look "up" towards the surface and use your "swim down" key. Since "down" is interpreted as the ventral direction (90-degrees from where you're looking) your avatar is pushed along forwards at jetpack speed but without the extra life support cost.

Since that adventure, most of my Nomad exits have resulted in unintended vertical excursions. Annoying. The hurry-up-and-jetpack idea doesn't seem to help,either. Drat!

You want to swim fast? Then use the jetpack out of water almost vertically, go as high as you can, then re-enter water at a visual angle of 30°, be sure to keep hitting W while entering water. You will then move very fast.
