All,

How frequently can you run a short script? In my case, it would simply disable fast travel. But more generally, I just wonder the most frequent time. Every minute? Every 10 seconds? Some other time?

I should really just see if I can alter the carriage script (which I havent looked at) and disable fast travel after every carriage ride. But in the meantime, whats the fastest safe frequency?

Thanks!

How much of an effect it has depends a lot on what you're doing and on how much else is also being done. Ideally the answer is "as often as necessary and no more", but that's often easier said than done.

Does this value often get reset? What can cause it to need to be disabled again?

Cipscis

For short scripts that are creating effects that the user is going to be focused on, I've found 10 times per second works pretty well without completely trashing the game. For longer effects, though, I would follow Cipscis's advice closely: don't do it more than you have to. You're much better off, of course, making the effect fire only when there's a chance of Fast Travel being enabled again.

can it not be changed in an .ini file?
