This tool automatically checks and updates your drivers to the latest version. Latest download for intel r hd graphics 4000 intel corporation - wddm 1.3 driver. The newer ones are still linked in a way, as everything the system does with the NVIDIA GPU, must go through the Intel GPU as a buffer, then go to the Display.Just download and install latest nvidia drivers in this case version 10. The fact that they are separate now, you can install each as needed and not have to be stuck with a certain version. The Intel HD and NVIDIA GPUs are completely separate and this is a good thing because unlike before (such as GT/GTX 300M series) they are allowed to use separate Drivers (with 300M they were only an OEM bundled Intel+NVIDIA driver package). The newer laptops with these GPU combos are different (as of GT/GTX 500M series) and no longer work as one with regards to Drivers. NVIDIA Optimus Technology is something older "Intel HD + NVIDIA GPU" laptops had where these two GPUs acted like one but auto-switched based on needs/loads. The NVidia processor was used to render games, and was listed in dxdiag under the Render tab. After installing the Intel card, the Microsoft Render device disappeared from both dxdiag and Device Manager, replaced in both cases by the Intel Card. In my case, the problem was resolved after installing Intel HD Graphics 4600, and then the NVidia driver. Optimus only works if you have the necessary drivers for both cards installed. Newer laptops use Nvidia's Optimus Technology to switch between the high performance Nvidia processor and the slower but more power efficient Intel integrated graphics. Terribly sorry to resurrect this thread, but I recently ran into this problem and seem to have found a solution, for anyone else having this issue.
