MGSV may be open world but it isn't packed with NPCs in the way a game like GTAV is, the former is also not as big as a number of open world games either (I've got and played the game heavily) as it's a collection of large areas which are only loaded for specific missions with maybe 20-30 or so enemy npcs so it's unfair to knock other games for not running at the same performance as these areas are nowhere near as large as the entire maps that a number of open world games run with loads of NPCs going about their business.
MGSV has made compromises itself to look and perform the way it does.
