Black Ops 2 Extremely Laggy

[Gninjaxd23]

Hey guys, just got a new computer!!!! BUT, Black Ops 2 can barely run!
So it all starts by me just installing Black Ops 2 on the new desktop. Everything loads fine, maps load extremely fast, which is nice, but then i change the settings. It's exactly same as my laptop, and the game is slow, moving the mouse, wait half a second, character moves. (Laptop Runs Beautifully at these medium settings)
Since this is new i might have to change settings? Though i cant understand why my desktop can barely handle BO2.

Specs:
ASUS-DESKTOP
OS: Windows 8 64-bit
System Model: M51AC
Processor: Intel(R) Core(TM) i7-4770-CPU @ 3.40GHz(8CPUS)
Memory: 16GB Ram
Graphics Card: NVIDIA Ge Force GT 625
ASUS-LAPTOP(One that works like a charm with BO2)
Os: Windows 7 64-bit
System Model: G74Sx
Processor: Intel(R) Core(TM) i7-2630QM CPU @ 2.0GHz( 8 CPUS)
Memory- 8GB Ram
Graphics Card: NVIDIA Ge Force GTX 560M

These are both the specs for both systems.
I am not a complete geek but i do understand a bit.

Any help will be much appreciated. Ty ^_^

your GPU is not for gaming.

What would be for gaming? .-. ( I don't know that much, told you. )

 

[daswilhelm]

your graphics card, is not meant for gaming (NVIDIA Ge Force GT 625). you'll need something stronger than that, something like a 760 or 770 would match your CPU. the only question is what your power supply is. since the system came with a 625, im going to assume you'll need to upgrade your power supply as well.

Would it be possible to switch the graphics cards from the Laptop to the Desktop?

no, definitely not. the desktop pc is not suited for gaming and needs an upgrade. if you have a budget for said upgrade, we can give you some options.
