Slow motion in WWE 2k15

There have been issues like this with other pcs as well. What we know is this; the game plays for 20 minutes and then dies because of space that is not being "closed" (removed so the computer senses about 60gbs of map instead of the normal 1 gigabyte), additionally the game will sometimes stop due to a certain animation or effect ie. shadows on buildings or a back stab. This is just because the game was loaded incorrectly or has a flaw in the system.

Model number of the laptop would help but on my packard either you can open intel integrated graphics settings and turn off "switching gpu to save power" or goto the power settings and turn off the change graphics card to save power.

Right clicking on desktop and selecting "configure switchable graphics" also works on my machine

Most laptops switch to dedicated gpu if you switch to high performance mode setting so try that as well...

Edit:I read that some of the newer laptops have a Fn key+dedicated button to switch between gpus, search if that applies for your model

while this info is for autocad, this page has a nice screenshot of switching the gpu in nvidia settings
