Agreed it does seem that FPS has taken a dramatic drop on this build. If you get in a tight spot where there are lots of torps close by its FPS hell.....
Also when many near are popping off their artillery.....
if only 3 or 4 in view it seems OK.... just any increase in stuff going on seems to have issues now.
I didn't have this problem at max effects on the previous CBT build.....
