@ HunterICX, well it kept nagging at me so I decided to remove all third party apps and reinstall the CCC, without touching anything I ran the game and was still stuffed! So I went through the 3D settings changing and testing then I found it, or more so you found it!
It was "Anti-Aliasing Mode" was set to "Multi-sample AA", I checked this by pressing Defaults and it slid back to "Performance" setting. I never deliberately set this so it was either from a third part app, accident, or register setting from previous install but I doubt that since I always remove old ATI references before installing,
so there you go, at least it all works again.
Thanks Wim, and thanks to All for the superb help!
