OfficerMod

This is something that only happens during lspdfr? If not, any recently added weapon models or car models could be the culprit. Installed a newer glock model off of gta5-mods.com and it broke my game (texture loss) until I removed it.

Look through your root folder for scripts or even the "script" folder, some scripts are known for causing drops in performance. I could barely manage 40-50 fps with my rig but that was until I realized I left Open Interiors in the directory.

There is a mod called Traffic Policer by Albo, it comes with various features to relocate a vehicle that was pulled over.

Are you familiar with ultimate backup? If so modifying the default lspdfr peds I believe is a similar process. Go to your lspdfr folder in your main directory and try to take a look at the agency.xml unless you have one in the "custom" folder. You may find your issue there.

Use Trainer V, in-game go to vehicle god-mode settings, go all the way to the bottom, enable vehicle always clean, uncheck all the other options and save. That's what I do for models that easily get dirty.

Try Assorted Callouts by Albo, I'm pretty sure I have one of those pullover/trafficstop callouts in my game and through callout manager it's under Assorted Callouts. There are also various locations for the callout.
