Cant run my assassins creed 4 at max settings without it lagging a bit.

[Guest]

I was wondering if my cpu was too slow or if maybe my graphics card wasnt good enough. How can i tell which one it is?
Cpu: intel core i7 processor i7-4770k, 3.5Ghz
Graphics card: Geforce GTX 760, 2gb gddr5

It's more than likely your gpu, I'd test this by overclocking my videocard by like 10%-20% for like a minute or two and seeing how much frames improve by, I will warn you without proper cooling you shouldn't really overclock at all, and if you do this monitor your temps closely.

So i would need a better video card?

The easiest solution and the most expensive would be buying a new video card, but no you do not "need" it.
Personally I would research around a bit, find if there are some optimizations you can do, overclocking is always an option.
It also looks like AS4: Black Flag is a bit of an optimized mess and some people have had luck with custom solutions.

In the second post the guy refers to downloading D3d overrider and getting a significant fps boost.
