So I've bought a PC copy of Overwatch last Christmas. I've been playing it on my very low end laptop, an Acer Aspire E15 with an i5-4200U(I think), a 920m and 4 gigs of DDR3L RAM, just fine for me(30fps capped with all settings on minimum) up until this Summer when I started having major frame drops, up to a consistent 5 fps. I was considering upgrading the RAM to 8 gigs. Would it help?
