fixed for me by
adding fc24.exe to Nvidia control panel and enabling vsync fixed it for me, this is my .ini file also
running at 200 fps no drops anymore, vsync isnt actually on in game however it does fix the issue, weird i know

No se olviden de entrar al panel de control de Nvidia y en controlar la configuración 3d van a configurar por programa, seleccionan ea sports fc 24 y solo van a la sincronización vertical y ponen activado
