On two of my planets (Shakok and Hephaestus) pipelayer takes a lot of time (up to 50ms per tick) when the camera is moved. The faster the camera is moved the worse it gets. On other surfaces it take around 1.3 ms which is still 4 times as much as on nauvis.

If other information are necessary or i can help in anyway with the investigation, I will provide it.

Some further testing showed, that it only happens for planets which already have stuff on when adding mid game. Will try to remember to do further testing when colonizing the next planet to see if the performance gets also bad, when it is enabled from the beginning.
What exactly does the mod do on player movements? I can't really think of anything needed for player movement.
