New build not doing so well in squad

https://pcpartpicker.com/list/LYFZLc

made this build in June of this year for about $1000. I’m loving it but I’ve been playing a lot of squad and have noticed the frames will drop pretty bad when I open my map, or randomly in general. I have this issue in bannerlord as well.

I understand squad isn’t optimized well but I made this build with that in mind. I play quite a few games considered unoptimized, I was sure this build would do well in them. Did I make a mistake? would you upgrade anything?)

Edit: fps drop from 100 fps to 55 fps in squad, 90fps to 50 fps in bannerlord
