This probably a dumb question, but I'm missing an obvious answer. I have a new Asus N76VZ 17" games/entertainment laptop. It has both integrated Intel graphics, plus an Nvidia Geforce 650M GT graphics card. In theory, the Intel graphics are supposed to handle normal tasks, and the Nvidia should kick in for games and applications with demanding graphics load. When I install and set up any game, the graphics quality always auto-detects the Intel graphics and set to "low quality". Clearly the game auto-detect does not activate the Nvidia card. If I manually reset the games graphic quality to "medium" or "high" or some other demanding setting, the games run at fairly low frame rate, and the PC gets red-hot - which seems to indicate that the Intel graphics are the ones active, and struggling under the load. The typical games (World of Tanks, Empire:Total War, etc) should be easily within the capability of this 650M card. I can't see any setting in the Nvidia control panel that might control the point at which it kicks in. Nor is there any apparent indication such as a tray icon to reveal when the card is active. I know the card is functional, as all of the system indications are just fine. Has anyone got a similar dual-graphics laptop and understand how the switching process operates?
