Persona 5 on a fairly decent system -> Horrible stutter and low FPS (~20)

Hi all, like the title says, I have a fairly decent PC, and I've tried all kinds of different settings but I'm getting absolutely horrible stutter and sub 24 frames per second  Any help would be greatly appreciated...

system:
i5 6600k
16gb DDR4 ram
Samsung EVO 980 SSD
Nvidia GTX 970
All drivers are up to date, as well as Win 10 pro

Set everything to default, SPU LLVM and Vulkan, then upload an actual RPCS3.log file following the Guide of this section
I've removed the copy pasta flood from the emulator window

Hi Ani, is this the file?
Thanks very much,

Set Preferred SPU Threads to 2 and update your GPU drivers
Other than that, settings are correct, you'll get the best performance you can get
