Edit: Also note that <2GB figure is with everything on MAX. With everything on minimum it probably uses even less!!
The game has some form of lock or whatever that it displays a prompt about how the system needs 6 GB of RAM and if you don't have that you are below specifications.
RAM usage so far (Task manager, unsure about VRAM.) is usually around 1.1 - 1.8 GB.
(Maybe it continues to grow the more you play, without unloading as maps change and such? Which isn't ideal.)
