Help me get more FPS on Persona 5 Royal pc version.

So I first tried the game in gamenative, and gamehub but couldn’t get more than 27 fps in both. Than I tried my luck with winlator ludashi and got 40 stable fps with only lower fps in like really crowded and big areas such as the place outside the subway station with the sakura trees. People online say that they get 45-60 fps but I get max 45-50 on inside places and all my settings are low in game and 720p resolution. One more thing is that I have the denuvo less version of the game and I should get better performance but I am not. My device is the Retroid Pocket 6, 8 gig ram model. Please help a brother out.
