Re: How do I enable my NVIDIA GeForce GTX 960 M graphics card?
In dedicated/integrated setups like Optimus, usually the built-in display will use the integrated (in this case, Intel) GPU. However, when graphics intensive applications, such as games, are ran, then it will auto-switch to the dedicated (in your case, nVidia 960M).
You can override this behavior for specific applications to make sure and force run it with the dedicated GPU, however. Open up the NVidia Control Panel, go to the 3D (or Performance I can't remember which), settings, and it should allow you to select options per application. Either find your application in the list or add the EXE to the list, and then set the option to "always use NVidia GPU" or "High Performance" mode.
Also, what games are you playing where they're "not very fast"? and at what settings are you playing them at? If they're graphics-intensive enough games, it could just be that the 960M isn't powerful enough to run them.
