Yea.. supposedly they built SWBF2 with this in mind. I remember the hype before it came out.. a person with a 64 MB graphics card could play it fine was the talk. But I'm sure that's with graphics turned down low and in single player mode. And I'm sure it's not integrated grahics memory with usage from the mobo.. it must be a seperate card. That's the only way I see it being able to work and you be able to still get good gameplay.
The real issues of lag happen for me in multiplayer. I can turn my graphics all the way up in single player mode. It looks incredible. But as soon as I get into multiplayer mode.. I have to start turning down the graphics to compensate for the lag. I didn't have that problem in SWBF1. Whatever they changed.. it sucks.
