Help me with "Can You Run It?"

I’ve been trying to avoid studying, and so I hopped onto Can You Run It? to see if I could run “Shogun: Total War 2.” It says “nope, your video card isn’t good enough.” But when I look, it has the “Minimum Attributes” of my video card, and I pass them all.

What’s the story? Should I spend the $50?

Are you running the latest drivers for your video card?

For that matter, what kind of video card is it? Is it onboard or standalone? If it’s onboard, it might be sharing memory with the mainboard and it might be thinking the video card doesn’t have enough onboard RAM for the game…

More info is needed…
