Lenovo Y580 with GTX 660m don't run dedicated graphics card as default's card

Recommended Posts

Hello guys, I tried everything from removing drivers, installing clean OS, configuring the nvidia control panel, and nothing works. I'm wondering if the dedicated GPU could be taken as main graphics card by Lumion or Rhino for small rendering. I know this card is not high end, but i'm pretty sure I can go betther with this one than the Intel 4000 HD. Pleage give me a hand here.

I just noticed I posted it in a wrong category, help me moving it please. Sorry for that.

Have we tried adding the executable of the program in 'Program Settings' under 'Manage 3D Settings'?

You could add the program manually and select the GPU in step 2.

 

Alternatively, if you right click on the .exe file for the program, you might see a ribbon option to 'Run with graphics processor'. From there you can select the GPU as well.

What is the state of the device in 'Device Manager'? Any errors? What version of the NVidia Driver software are we running?

Did you set the graphics to "switchable graphics" in BIOS?
