Help with performance

Hi, i bought the game two years ago and back then it used to run nicely at around 60fps on high-ish settings, so now i wanted to play it again however when i went to benchmark it, it struggles to reach 30 in populated zones and barely gets past 50 on fields. My hardware is still al the same appart from the better cpu that i got since then, i dont get why this is happening.

I5 7400 3.00GHz
8gb ram
