Windows 7 Not Detecting Nvidia Card. Gt70 670MX GPU.

Question

So I downgraded from windows 8 to windows 7 and have recently discovered my computer is using the Intel HD 4000 instead of the correct Nvidia 670MX. When I disable the Intel Hd the system restarts and displays stuff but the nvidia program says it can not detect an nvidia gpu. When I re enable, the nvidia driver detects the gpu but does not use it (directx diag shows the intel hd 4000). Any help would be greatly appreciated because I would hate to have to reformat back to windows 8.

Answer 1

Dxdiag will not use the NVidia card. Ignore it, as it's stupid to rely on it for anything.
You can't use the NVidia card 100% of the time. You need to use the Intel HD4000 when you're not gaming, as that's what it's meant for with Optimus.
Sometimes you need to make sure that it is switching to the NVidia card when you need it for a game or for whatever it is you're doing that you need it. This usually involves making a custom profile within the NVidia control panel. I have not played a game yet where I did NOT have to add it. I'd add it anyway, just to be sure that it's working correctly. Once you add the game, and tell it to use the NVidia high performance adapter (instead of the Intel integrated adapter), it should work just fine and hopefully increase your FPS.
