Has anyone had any luck in getting SimCity 4 to use the discrete NVIDIA graphics card (as opposed to the integrated Intel card) on laptops with NVIDIA Optimus? Even though I've gone into the NVIDIA Control Panel and manually configured SimCity 4 to use NVIDIA graphics, the game still insists on using the Intel card, and performance suffers a great deal as a result.   (For those of you who don't know, NVIDIA Optimus is a battery optimization technology that automatically switches the graphics card in use depending on what you're doing; that way you can preserve battery life by using the low-performance card when you're not doing something graphics intensive, like playing a game.)   EDIT: Using the option "-d:OpenGL" seems to force it to use the NVIDIA GPU; my GPU light changes and the NVIDIA card is listed in the config log. Unfortunately, it's not really playable because the graphics aren't being rendered properly.
