Extremely low framerate

Hello, I'm new to using forums so I apologize if I do this incorrectly or I'm posting this in the wrong place. Either way, I have installed LSPDFR earlier today and at first It was running fine. I added some callout plugins and some replacement police vehicles, and a speed radar plugin. Other than that, I only have a few mods which I'll list what they do: A gore overhaul mod, RAGEuphoria ragdoll physics, and weapon sounds and ELS. With that out of the way I'll get to the issue at hand. I have had the same plugins and mods throughout my playthrough, changing very small variables when I do make a change (ex. changing a keybind in the text file for the speed radar.) After loading up the game after closing it previously, I have had extremely low framerate. I changed my graphics from ultra to as low as possible and that fixed the issue for a short time, but when I closed and re-loaded the game to make sure it was fixed, It was back to a low framerate. (The graphics did not reset back to ultra, I checked.) If anyone has any suggestions on how to fix this, It would be greatly appreciated.
