Twisted Metal [BCES01010] - Abnormally poor performance

Hello! I'm looking for help making Twisted Metal playable. I've emulated some-40 games so far and they've all ran perfectly or at least in a way that's completely satisfactory, even with 60fps patches. But for some reason I'm only getting around 10fps in this case. Ever more puzzlingly, most videos running the game on RPCS3 are 2-3 years old and are running the game just fine at a stable 30fps. I've pretty much tried every configuration and even tried rolling back to a previous version of the emulator, but the performance never improved.
My specs:

Processor AMD Ryzen 5 3600 6-Core Processor, (12 CPUs),  ~3.6GHz
NVIDIA GeForce RTX 2060 SUPER (8GB VRAM)
32GB 2133MHz RAM

Does anyone have some advice? Thank you!
