Windows 7, 2.0 Dual Core yet, I have lag?

So, I just bought the game, started it up and all that. I crashed on the first try because I had advanced graphics disabled. I have Intel HD Graphics® card, which I know isn’t the best, but should be able to handle this game right? I can run Rome Total War, so…it seems I could run this. Should I try updating/downgrading Java? Or should I run it in compatability mode?
