    Hi, I'm not sure if there is a problem but I can't figure it out. Here is the situation. I just bought a Toshiba Qosmio X875-Q7380 laptop with Win 8 and the laptop seems a bit slow on the graphics part. It came with an Nvidia Gforce GTX 670M which is pretty good. The problem is that in the device manager I see also an Intel HD Graphics 4000 adapter.

    When I run the Windows Experience Index the result is 5.6 becasue of the HD and that's normal. But the Graphics is also low at 5.9 and it shows the Intel adapter instead of the Nvidia. My old laptop an HP Pavillion DV8-1010el has a GT 230 with with less memory only 2Gbit and it's 6.4.

    I tried running a heavy graphics program on both laptops simultaniously and the risults were tottaly different. The old finished in less than 10 seconds and the new took over 40 seconds. I looked a little closer and found the the new laptop only had 32Mbit of dedicated graphics memory so I'm pretty sure it's using the Intel graphics adapter, the Nvidia should have 3GB.

    My question is how can I force the Qosmio to use the Nvidia card instead of the Intel.
    Thanks....

    The machine has dual graphics. It defaults to the one integrated in the CPU. If you want a program to use the Nvidia processor you have to specify this in the Nvida control pannel.
