My brother has finally given up and gotten Steam, haha (it was the new Monkey Island games that did it). He called me last night and told me he was having a bit of trouble with slowdown in one of the games he's downloaded, and I figure (though I haven't gotten the chance to go take a look at his computer yet) that it's probably a graphics card issue, I don't really know anything about what he's got under the hood except that he got it from Fry's as an HP premade, probably about a year ago. I can't be 100% it's the graphics card, but I know my brother- he probably went for more of a multimedia package than a gaming machine.
I told him as a temporary measure to go into the video options and turn off anything like water effects and AA until I was able to take a good look at his specs.
Anyone have any recommendations on a graphics card to suggest to someone who isn't a hardcore hardcore gamer but still wants some decent performance? Will update this topic as I learn more about his rig.
It just occurred to me that he might not have the latest drivers for his graphics card too: I'll have to ask him about that.
