Speed across land and water in your own personal hovercraft. 2 versions, plus 2 more with the mod 'Laser Tanks'.
Mods introducing new content into the game.
Transportation of the player, be it vehicles or teleporters.
Just installing the mod makes it the most cpu-intense mod (I have about 70 mods currently active) - no hovercrafts in use.
I'm experiencing the same thing! I don't have any hovercraft deployed in the map and this mod uses much time to update (> 0.1 in 'show-time-usage')!
Thanks.
It does currently have a fairly high consistent use, but it will stay constant, so isn't a massive deal. Regardless I've improved this by caching mod settings in my PR: https://github.com/ArcaniVictus/Hovercrafts/pull/5
The PR has been merged, thanks for your contribution!
