This driver has better performance and stability for Gen 7 and older hardware. mesa-amber is the legacy Mesa package which includes the classic (non-Gallium3D) drivers for Gen 2 hardware and later.This is the recommended choice for Gen 8 and later hardware. mesa is the up-to-date Mesa package which includes the modern Gallium3D drivers for Intel's Gen 3 hardware and later.Install one of the following packages, which provide the DRI driver for 3D acceleration.See Xorg#Driver installation to identify your card.
Intel's Gen N hardware does not refer to the generation of the CPU, it refers to the generation of the GPU, which is different from the generation of the CPU.PowerVR-based graphics ( GMA 3600 series) are not supported by open source drivers.Just start a game, do stuff and then Alt+ Tab over to see which GPU was busy. If you feel performance is too low, you can take a look in Task Manager’s In your case that’s the Mini-DisplayPort connector and the HDMI connector. Some laptops, like yours, also have connectors that are going directly to the dedicated GPU. When the dedicated GPU is used, it sends the finished image to the low-power GPU for displaying it. Otherwise, the dedicated GPU could never switch off. In Optimus laptops, the integrated display is always connected to the low-power GPU. Some games show in their options menu which GPU is active. This is especially useful for programs where you can’t bring up the context menu like this. The last option will bring up the NVIDIA control panel, where you can add a program and change the GPU it should use. (It’s in German for whatever reason, but I think you’ll get the gist.) You can do this on a case-by-case basis in a program’s context menu: Sometimes you may want to override this behavior. Usually, the built-in logic is good enough at detecting when to use the dedicated GPU. It is a technology that allows you to use an energy-efficient GPU for day-to-day work while being able to seamlessly switch to a powerful dedicated GPU for gaming or other demanding tasks.
