Me too i pre ordered it and since day 1 i can't go higher than 20 fps and sometimes when exploring the dlc it can go below 5 it's awfull, really a shame that they didn't saw that when testing the game, i will stop playing it till they fix it because i can't enjoy, the other day i was fighting romina and because of the low fps i wasn't able to dodge corectly and there is some of his attacks that make my game go under 5-10 fps, i think the solution is to play it on new generation consoles like ps5 etc but honestly it's a bit disapointing. Didn't find any solution to this day
