Basically any time the map view orbit nodes are changes or added there is a momentary spike in performance where the game appears to freeze for a moment. This is presumably more noticeable on less powerful machines.

This can be recreated by putting a vessel in orbit, then making a maneuver node, or targeting another vessel, or planet, or generating an encounter while editing a maneuver node. Anything that adds something like the closest encounter map node icons, or generates another orbit line like adding a maneuver node.

This behavior is not present in KSP 1.4.5.

Whenever I am setting up a maneuver node there is really bad lag (2-3 seconds) when the maneuver detects an encounter. If there is no encounter detected, things projected trajectory changes are smooth, once the encounter is detected everything freezes for a few seconds and then jumps ahead, once the encounter is displayed things are smooth again until the encounter ends and another lag. This also occurs when I am executing the maneuver and my current trajectory detects an encounter. Very annoying when trying to plan and execute precise maneuvers!

- Career mode, mid game, was fine before upgrade to 1.5
- I do have one mod installed "For Science", that's it
- I started a fresh new career mode game and there was no lag with the new game, lag still present with the "in process" game.

Performance has been improved up to 1.7. Setting this bug to RTT to have the reporter verify if this issue is still valid.

I certainly noticed the delays in map-view in version 1.6.1, and notice no delay at all in version 1.7.0
