Please try disabling the integrated graphics at the system level and running it with the dedicated GPU only.

Thank you so much for your help! Your suggestion worked perfectly. I changed the game to use my dedicated NVIDIA GPU instead of the integrated graphics, and now the FPS is much smoother. I really appreciate your quick response and all the work you've put into this game. Thank you, and keep up the great work! ❤️
