HELP! GPU on windows 7 cut in half???

[ambaris87]

On my new iMac I installed windows 7. So for a while now I have been trying to run witcher 2 and no matter what it runs slow. I went to the website Can I Run It and it told me I could not. Upon closer inspection it told me I only had 229 video ram not my actual 512mb?! So I checked it for myself in my system and it was true. For some reason in windows 7 it is not using all of my GPU please help I am dying to play witcher 2 heh...

You install windows in bootcamp or VM.

... I know how to run windows 7 through bootcamp. My issue is that once everything is working windows is only recognizing 229mb not the full 512mb of my GPU. I found this in "dxdiag" on the display tab.

1. Install new bootcamp drivers (3.4)
2. Install latest GPU drivers from manufacturer (don't install one promoted by an ad!)
