For some reason, and it's a long shot, when playing Dark Souls 3 last week, I left Chrome open because I couldn't find out where to go, so have the IGN Walkthrough open (no shame, hahaha). Despite plenty of memory available, and the processor running at less than half of it's capacity, I noticed at the task manager that the only page opened on Chrome was marked as 11 processes (?). Still, just over 1.2GB, but plenty available. As soon Chrome was closed, no stuttering. Just as a side note, Dark Souls Caps the FPS to 60, so all my system runs as if the game was a spreadsheet. No real load.
