![]() Switching the video outputs always produced an annoying flickering on the display. The "switchable graphics" have improved over the generations but a few grave system-related disadvantages remained. Because of that, buyers had to live with the included drivers and can't benefit from performance improvements and troubleshooting of the newer driver versions. For each laptop this proxy driver was built again with a significant effort and never updated again. Besides that, these solutions use a proxy driver (required by Windows XP and Vista), which unite the graphic drivers from Intel and Nvidia. These multiplexers demand a lot of place on the mainboard, extend the signal path and, also always need a bit of electricity. Up to now switchable graphics (from Nvidia and ATI) use multiplexers to route the between the graphic card outputs and the display ports. To combine both advantages, the user also had the possibility to choose a laptop with switchable graphics. Without switchable graphics, the potential laptop buyer usually has to choose between performance (with a strong graphic card) and a long battery life (using a graphic card integrated into the processor or chip set). ![]()
