As of a few patches ago i was able to play shoreline & customs with no problems even on my low end PC
With the present patches shoreline & customs are unplayable with Insane stuttering do to the memory leaks with lower end riggs with 8 gigs.
I found a temporary solution that made my PCs run Both maps fairly well again. I hope this works for you.
i5-2500K Processor 3.3 GHz - 8 gig Ram - 1070 gtx 8 gig

Go get a cheap 4.99$ 4gig flash drive.

This is not a miracle cure - just a temporary fix tell next patch. ( I hope? )
