[Question] Bad sniper scoope fps

So, I have had to turn my graphic settings a lot to even play this game at 40-50 fps in 64man fights, and today I had the joy of finally getting a sniper slot. An to my horror when I scooped in, I went from 45 fps to 10...

Any ideas or fixes would be nice, here is some of my basic pc's info:
