Why is my graphics card so slow?

I recently purchased the Lenovo Y510P. This laptop includes 8gb memory, intel core i7 processor, and a nvidia 755m graphics card (no sli). When I play NBA 2K14 I only get 10 FPS! Online it says I should be getting over 50. What's wrong with the graphics card?

Run with the power cord plugged in.
If it is already in, unplug and replug.

Sometimes the laptop graphics card go into powersaving mode on battery, or when it thinks it is running on battery.

You can try updating the graphics driver, please install the graphics driver from the official website and download the latest version.

Try to upgrade the RAM.
