Assassin's Creed Syndicate RAM issue?
You're confusing the RAM in your system with the RAM of your GPU. Your computer itself has 16 GB of RAM that are used for general computing. Your 1050 has 2 GB of dedicated memory that's directly on the card and is exclusively used by your GPU. Note that there isn't even a 16 GB model of the 1050. 16 GB is an insane amount of RAM for a GPU, to the point that right now I am unaware of any consumer-grade GPUs with that amount of RAM (apart from maybe the Titan RTX, but that GPU costs so much it's hard to consider it consumer-grade).
