Help with setup (Persona 5 Royal)

Good day .
Already completely desperate, and decided to create a topic here, all of a sudden someone will tell you.
If a similar topic already exists, please share the link - I did not find it myself.
In connection with the upcoming translation of 5 persons, I purchased this masterpiece in the incentive, and decided to immediately check how it is there, robbing or buggy, and it turned out not in vain. In the main menu, fps jumps from 8 to 14, while running it is at the level of 25, and in battle it rises up to 40. At the same time, all videos and downloads work stably at 120. The fact is that I have NEVER encountered such a problem when one particular game sags. Changing the in-game settings did not have positive dynamics, like all my other manipulations.
Iron should pull this whole structure without even straining: RTX 3060 Ti, 32 RAM, AMD Ryzen 5 2600 Six-Core and more.
Can anyone give some good advice?
