I recently bought myself a gaming laptop as an upgrade to my old desktop and every game (such as WoW) runs fine with my graphics card playing them all perfectly at high settings I installed Diablo 2 on this new laptop and saw that it was extremeley laggy with horrible frame-rate This was due to the game using the integrated graphics rather than the dedicated graphics card. Using the Nvidia control panel it did not allow me to set my GPU to run Diablo 2 and has grayed out the option to select what graphics I can run it with. In the grayed out box it shows that it runs it with my integrated graphics. This makes the game unplayable as without importing my previous data and testing out a new character even walking around Tistram gives a unplayable frame-rate. I am running this on windows 8 but this should not be the problem as it runs the game as it should the only problem being the GPU itself. I have also used the in-game patch and also run it as admin and also running it with right click selecting the Nvidia GPU. However upon the game playing it runs it with the integrated graphics. I have also updated all the GPU drivers in the device manager just incase that was needed. This laptop was already updated with the latest drivers. My GPU is a NVIDIA GeForce GT 635M I have also provided a screenshot of my NVIDIA control panel regarding Diablo 2 : View attachment 4047 Help would be very much appreciated.
