Tips for boosting perfomance in LSPDFR 0.4?

Hi, dear fellow officers, deputies, and sheriffs. I'm coming to you with a request to share your tips for improving LSPDFR 0.4, which has a demanding plugin installed.

My base LPSDFR plugins (must-have for me) are - Traffic Policer, LPSDFR+, Interaction+, PoliceSmartRadio, Search Warrant, Simple CPR, Arrest Manager, Callout Manager, Ultimate Backup and SpotLight

For my base callouts, I use these 3 - Agency Callouts, Assorted Callouts, and callouts from Traffic Policer

My current PC specs:

CPU - 8 core Intel Core i9-11900H, GPU - RTX 3050 4GB 60W, RAM - 16GB in dual channel with 3200MHz, Disk - 1TB+2TB SSD. Yes, it is a laptop.

I set population variety and distance scaling to zero and changed DirectX to 10 to minimize antialiasing. I also set Main.PreloadAllModels to false. When I boot up the game, everything loads up fine. After 15 minutes of playing FPS drops from stable 45 to 30. After another 30 minutes, FPS varies from 15 to 30FPS. I have set the CPU clock speed to base 2,5GHz (because the CPU overheats in my laptop, when I boost it to 4,8GHz). If I eventually boost the CPU clock speed to its maximum I gain FPS back to stable 30. But after another half hour of playing it again drops to 15-30FPS. If I lower the CPU clock speed back to 2,5GHz the game drops to 5-10FPS. The most heavily demanding plugins here I suppose are Assorted Callouts and Ultimate Backup. Plugins themselves work without any issues and during testing, I haven't noticed any crashes whatsoever.

I honestly don't know what to do. I had a similar setup in LSPDFR 0.3 with my GTX 1050Ti and it was playable. Is LSPDFR 0.4 that heavy demanding, if more plugins are applied? No, I do not want to use Stop The Ped as it causes even more stutters than all those plugins combined (I don't know why, but I had the same issues on my GTX 1050Ti as well).

I was thinking about using the DLSS mod from PureDark, but I had issues with borderless mode - my screen is 2880x1620 natively and neither 1920x1080 nor 2160x1440 doesn't work well. Any tips for other improvements? Thx for your help in advance!
