Change the plugin timeout threshold from 10000 to 60000 in the RagePluginHook.ini file and change Main.PreloadAllModels in GTAV/LSPDFR -> LSPDFR.ini to false.
Also, remove in /Plugins/LSPDFR:
- PeterUCallouts;
- Regular Callouts;
- RichsPoliceEnhancements;
- XScanner

For more memory; simple install those 3 files.
Gameconfig; choose 1x Traffic 1x Peds or 1.5x: https://www.gta5-mods.com/misc/gta-5-gameconfig-300-cars

To downscale textures of a car, first check the size of the .ytd / hi.ytd.
If it's below 12MB, it's fine. If it's above 12-16MB, it's too high.
 
Extract the textures via OpenIV from the .ytd.
Use GIMP, PAINT or PhotoShop to downscale the textures.

First off, make sure Main.PreloadAllModels in GTAV/LSPDFR -> LSPDFR.ini is disabled.
Secondly, I see you're using a visual mod. While your framerate looks alright, I still recommend to give GTA V more memory allowance.
 
 
And thirdly, if you installed high-poly police vehicles, downscale their texturs.
