The FPS drop is caused not by just one or two scripts. It's just how much the scripts comunicate between each other.
This explains why, for example, during pursuits the FPS drop increase.
If you're looking for a fix, well, I think more RAM should make the game go smoother.

Just a week ago, we released LSPDFR 0.4.  Since then, there's been at any given time an average of 620 people playing LSPDFR, peaking at just over 1,200 earlier today.  We think these are pretty incredible numbers for a game mod, and we've really enjoyed watching as people get to grips with 0.4 and all of the new possibilities it offers.
 
With that being said, we've been monitoring the support forums and have recognized that there are, of course, a couple of issues with 0.4.  We're working to get as many of these sorted as we can and hope to release a small patch to address the most important ones shortly.
 
Today, though, we're introducing two new features as part of LSPDFR Sync - the Activity Feed and the Companion App. 
 
Activity Feed
The Activity Feed, in a bit of a throwback to the days of LCPDFR's Crime Statistics, is a live activity wall of everything that's going on in LSPDFR 0.4.  You can track what your fellow officers are up to with live updates on callouts, traffic stops, arrests, etc.  Plus, we've integrated it with the website so everything is linked together nicely as far as Characters and forum accounts go.

Companion App
The Companion App is something a little different that we're working on.  Open it up while in-game and you'll see an overview of your current session with your Character's location marked on a Google Maps style rendition of San Andreas.  As well as some basic info about your Character, we've added a couple of actions that can be performed from the app such as calling backup and going on and off duty.

It's early days, but we definitely have some cool plans going forward for the Companion App.
