I installed VMWare on my new Macbook Pro. It's running 64-bit Windows 7, and I have Steam downloaded within Windows. I can't play games like Portal or Black Ops 2. With Portal, it says my video card is unsupported and I should update my video drivers. With Black Ops 2, it says DirectX has encountered an unrecoverable error and just doesn't go further. My Macbook Pro has an AMD Radeon HD 6750 Graphics card inside of it. I will admit I know nothing about PCs and have no idea how to download a graphics driver. Furthermore, I downloaded AMDs program that can automatically detect your card and update the driver, and it said it couldn't detect my card. I could use some help. Thanks!
