I've bought this notebook a few months ago, everything worked fine. It has a SSD harddisk and Nvidia Geforce GT650M (1gb). After doing some 3D modelling with my Nvidia GPU I tried a rendering program to make my 3D model look realistic. But while running Lumion (render program) my Nvidia GPU won't get active. I checked my Nvidia settings, everything looks like it seems to be. Lumion is set to run with my Nvidia GPU, but it doens't. Sadly it works whenever I try to run Chrome with my Nvidia GPU, so I don't know what the problem is. Hope you guys can help, I added a screenshot to my post, so you guy can see my problem.
When I came home, I tried to run Lumion on my brothers Notebook, which has a normal harddisk (7200RPM) and a Nvidia GT555M (2gb) and everything works flawless on his. Even adding Lumion to the Nvidia GPU using list.
