So my computer has two graphics cards, one for all the normal stuff I do, and then it senses when I start using photo editing software or playing a game or an HD video, and it switches to the higher graphics card. I don't think it's communicating with Parallels, though.

I have a game installed on my Mac, and I installed it on my Windows 7 VM as well, as the whole point of getting Parallels was so that I would be able to modify the game, which i can't do on windows. However, I can't launch the game in Windows, as it claims it can't find a supported grahpics cards. But it has no problem running on the mac side, so it can't actually be my graphics card?

Where is the miscommunication happening?
