Intel 82945G Game Requirement Analysis
Intel 82945Gcomes embedded on the Pentium 4, Pentium D, Celeron D, Core 2 Extreme, Core 2 Duo CPUs and features an Integrated GPU called Intel GMA 950.
It only supports DirectX up to 9.0c so DirectX 10/11 games aren't (hardware) supported. The performance is quite bad and even very old games (before 2005) might require reduced settings. Today's games are, obviously, unplayable.
