Aug 17, 2013  I have a iMac with a ATI Radeon HD 4670 GPU. In CS6 the 3D mode is grayed out and disable due to driver for GPU needing to be updated. When directed to manufacturer website for driver update, all drivers are for Windows, not Mac.

I initially planned to purchase Black Ops for Mac from the Mac App Store for my late 2009 iMac. I was thinking I'd then buy GameCompanion and connect an Xbox 360 controller to my computer, effectively making it an Xbox.

Unfortunately, I just checked the machine's specs, only to find that I have 256 MB of video RAM instead of the recommended 512 MB. The exact card is the ATI Radeon HD 4670 256 MB. If I did purchase the game, would I notice a severe amount of dropped frames, making gameplay really frustrating? If so, are there quality settings in the game I could turn down? Also, could the use of a wireless controller create additional lag? Any advice appreciated. All machine specs are as follows.
