Assassin's Creed IV Black Flag lag

[arielg14]

I bought an HP laptop

Microprocessor - Intel Core i7-4702MQ with Intel HD Graphics 4600 (2.2 GHz, 6 MB cache, 4 cores)

Chipset - Intel HM87 Express

Memory - 16 GB 1600 MHz DDR3L SDRAM (1 x 8 GB, 1 x 8 GB)

Video Graphics - NVIDIA GeForce GT 750M (4 GB DDR3 dedicated)

Hard Drive - 1 TB 5400 rpm SATA

I am trying to run Assassin's Creed IV Black Flag and i noticed that there is a small lag, i tried to reduce the graphics and it is still the same it's like the game is not optimised.
it happened before with other games and when i run the games through GeForce Experience the games were working fine, this specific game (Assassin's Creed IV Black Flag ) is not appearing in GeForce Experience game list,
i think that the laptop is strong enough to run the game without any lag,
what do you think?

No, your laptop isn't strong enough to run the game without lag. The GT750M is comparable to a GT 640 desktop card. It's a low-end card not meant for heavy gaming.

ACBF isn't that well optimized, but it's also not that badly optimized. You mostly have a weak video card.
