Hi,

I got an SB 2 with i7, 16GB and the GTX. Both GPUs are shown in the device manager.

If I disable the Intel GPU - which means there is only my GTX activted - the screen output of windows gets laggy and my screensaver is doing like 2fps.

It seems like windwos is not accesing to the GTX. If I do some benchmark, there are still two gpus shown

GPU 0 Microsoft Basic Display Driver

GPU 1 Nvidia GTX 1050

For this reason I disabled also the GTX - means the Intel and the GTX are deactiveted - the windows output ist still the same and shows the same laggy screen. The reason I got this for is, Im trying to start some applications with die dgpu, but theys doesnt run with it.

Does anyone get the same issue?

    It seems like you are trying to use the Nvidia GPU as the display adapter. That is not possible.

    The correct method would be to use the Nvidia control panel to select which GPU to use for a particular application. In some cases you will be able to right click the application and select the GPU that you want to use.
