Demon Souls runs in fast motion

Hi guys.... I have this problem: after do the configuration just like Whatcookie says in: https://rpcs3.net/blog/2019/08/12/new-de...fps-patch/ the game runs perfectly fluid and with 60 fps, but.... its move really fast! like in fast motion camera.... wich make imposible to play. I don´t know what to do already....

My PC:
        Intel Core i5-4440 CPU  3.10GHz
        RAM: 16Gb
        GPU: Radeon RX 570 4Gb

Thanks!!


PD: Also I have to say that, this is the only configuration where the game works (the Whatcookie config), in all the others configs. I have tried, the game does not run smoothly and I have thousands of other problems (such as fps drops, freezing, or frame to frame movements)
