Unfortunately, this did not help either. Still stuck around 30-40 FPS, which seems absolutely unreasonable for an i9 9900K, 32GB of RAM, and a RTX 2080 Ti. It happens as soon as LSPDFR loads, and when it's not running (or crashes lol), then it shoots right back up to 120 FPS.
I don't even know if LSPDFR is recognizing some of those commands, for example "Callouts.DisableBigRadar" I assume is supposed to stop the map in the corner from going big when a callout comes in, right? It doesn't.
