I've done some research by testing other SPU options. I've noticed that SPU Interpreter dynamic slightly improves the performance over ASMJIT, although this does causes a huge audio slowdown when enabling these options.
ASMJIT: 15.3/16.8/18.1 FPS
Interpreter dynamic: 16.4/17.4/18.5 FPS
Interpreter static: 10.5/12.2/13.2 FPS
I've ranked each SPU options from slowest to fastest:
The ASMJIT performance seems to have regressed when enabling RSX tiled memory, while the LLVM performance works totally fine.
I am getting opposite effect on my "lower end" system that struggles to play the game (Ryzen 7 3700x), with tweaks enabled to fix graphics I get 10 to 8 FPS with ASMJIT then with LLVM 12 to 10 maybe less than it should be not sure but more. Upgrading my CPU soon though hope I can play this game at playable FPS soon graphics look fine now
Quick summary
Using LLVM recompiler runs significantly slower than ASMJIT.

Heres the performance comparison between LLVM and ASMJIT.
LLVM recompiler: 9.2/10.8/11.8 FPS

The strange thing about LLVM is that it's supposed to be faster than/tied with ASMJIT, which is why I thought it would be necessary to post this bug.
