I dislike Bugs... Like a lot.

So I just got fallout 4, and bear in mind I know nothing about this franchise as this is my first Fallout experience ever. I started playing and encountered a thing called a radroach?, but how many big bug monsters am I going to encounter, because I absolutely despise larger than normal bugs in video games. and if it's a lot should I keep playing despite this or am I just going to hate it .

Also side note. my game feels really choppy when I turn for some reason anyone know how to fix that.
