I have a Packard Bell gaming laptop. It's an i5 quad core, has 12 gigs of RAM, and GTX 750m.

The problem is that it has Nvidia Optimus, a feature that lets the Intel HD Graphics be the primary graphics processor while not using heavy 3D demanding apps and games.

I just bought Daylight (Super Keen), and it won't run because when it checks for system specs, it uses the the Intel GPU (which doesn't support DX 11 apparently) instead of the GTX card. How can I fix this?

  • Can you temporarily turn Optimus off? I know AMD has a similar feature, where you can "optimize game for performance" (GPU) or "optimize game for battery life" (IGP).

  • I have absolutely no idea how to do that with nvidia optimus. I went throught the geforce settings and couldnt find a function like that

  • I looked into that. I believe that may be the problem. There is an update for them in windows update but not in geforece(weird). I believe the drivers may be outdated. Just out of curiosity, would an older display driver not work with newer directx?

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


  • It worked. I updated and could start the game. I'm not sure if i should make a new thread for the next question, while a new story loads i get an error of mvcr100.dll is missing. i did some research to this error and the solution came to reinstalling visual c++. I did that twice(64bit, 32bit) and it still didnt work. i did install them after testing to see if one install worked.

  • That isn't related to graphics card switching, it's a function of the version of visual c++ that the game uses. install the version of visual c++ that the game recommends and you should be golden May 21, 2014 at 6:54
