Intel 82915G Game Requirement Analysis
Intel 82915G comes embedded on the Pentium 4, Pentium D and Celeron D CPUs and features an Integrated GPU called Intel GMA 900.
It only supports DirectX up to 9.0c so DirectX 10/11 games aren't (hardware) supported. The performance depends on the CPU it's embedded since Pentium 4 only supports DDR and Celeron D supports DDR2. Therefore, the memory bandwidth is quite different.
Today's modern games are unplayable, even at the lowest settings.
