Hello, Recently I've been having a problem with the Second Life Viewer (and several third party viewers) not running on my Nvidia chip, instead running with the integrated GPU. I have made sure that the default graphics processor is set to my Nvida GPU, and I have tried doing a clean reinstall of the client. I have a Toshiba Satellite p750 with a Nvidia Geforce 540M, and run Windows 7 Home Deluxe. Thank you in advance, Matathia.
