Heroes V performance on a laptop.

Thank you to everyone who responded. I was just wondering, I recently installed Black and White, but it wouldn't work, and then I read on the licensed box that it's not guaranteed to work on integrated graphics. Then I bought a demo of Heroes V on CD, installed it, loaded the menu, and spent five minutes watching some horse animation, and it was all like a slideshow. And I read somewhere that it's not guaranteed to work on integrated graphics...

What makes owners of integrated graphics cards any different? Why is there such unfairness? (rhetorical question, no need to answer):)
