I have a railgun turret in a mod I'm producing and for some reason it can shoot one shot and then the frame rate starts to plumet; if removed the frame rate returns to normal.
No special LUA is running on it, its just a long range turret (500m) with a low firing speed.

If the range is 500 then it's going to need to scan a 1000x1000 tile area around its self for things to shoot when it gets ready to shoot which is going to be slow.

Don't make the range 500 - problem solved.

hmmm. I guess that is a bit excessive. so the math on that is range x2 ^2?

But wouldn't that also mean that the frame rate should drop upon placement, as well? Because the scanning for enemy targets should be constant upon placement, why would the frame rate drop when scanning after a shot is fired but not after being placed on the ground? Is there something different that occurs once a turret has fired its first shot?

I believe the math would be a lot closer to pi * radius^2, as if I understand correctly, turrets have a circular firing area. With a 500 tile range, though, that's still a lot of ground to cover.

Scanning only happens when an enemy is within range to fire else the game's performance would go to garbage with more turrets placed.

Ok. so does that mean that scanning is for detecting info on all enemy targets within range once an enemy has crossed the range threshold? Just trying to reconcile the game's behavior of my own preconceived notions of how I would interpret the functionality.
