Finally if we look at an S3 Unichrome ( or any other AGP integrated part ) the list becomes much, much larger - so much so that you should just suppose it won ' t run, no matter what it is. But many people can attest that a lot of games that are high - requirement ( such as; NFS: Most Wanted, Half - Life 2, and Painkiller ) run just fine on an X200M. The Doom 3 engine falters just because ATi ' s OpenGL support is nonexistent. Otherwise you can not explain why HL2 is running fine at 1280x768 high detail while Doom 3 can not stay above 30 fps no matter what. Doom 3 might well be playable on nVidia ' s IGP, the Go6150, given nVidia ' s traditionally great support on OpenGL drivers.
Dedicated GPU:
Only two companies are currently manufacturing dedicated graphics chips: ATi and nVidia.
These card feature more hardware support for advanced DirectX 9 and OpenGL 1. 5 functions. Most importantly, they get that name of dedicated graphics cards from the fact that they use exclusively dedicated Video Ram, ensuring smooth and snappy performance. The problem is that dedicated video cards use much more power than integrated chips, resulting in more heat and shorter battery life.
