Well, I'll try at least. But this isn't something new. I've had it like this for at least a year. 
Nope, that didn't work.
I'm pretty pissed off about this because iv'e lowered my settings to high so now I get 80+ fps off duty. But when I get on duty in a pursuit etc I drop to around 40 fps. I've had this issue since I started playing LSPDFR and that was late 2016. Now we are in early 2018 and there still haven't been a fix. If someone can't find a fix for this I'm leaving lspdfr and it's community. 40fps and I don't even have any mods or plugins/scripts installed except from LSPDFR. Jesus.. 

Just installed LSPDFR and latest ragepuginhook on latest version of gta v. Note that except from these two I only have scripthookv, scripthookvdotnet and simpletrainer installed. 
I'm struggeling with the frame rate and have done that for a very long time. Off duty I have around 60-70 fps on very high settings no MSAA. But as soon I go on duty my fps drops to 40-50 fps. I remeber that last time I played LSPDFR I Only had around 30 fps. At that time I had multiple callouts, els and some of albos mods installed. Right now I have non of it. And I still get only 40-50 fps. So, is this normal? Are everbody else having this ''issue''? And if it is fixable, how? Thankful for answers! :)
