I'm relying on someone with greater experience using Vista on a Mac might assist me with this relatively minor problem. I picked up a new 3.06 gHz iMac yesterday and although I don't use Vista I decided to install it as I had acquired Office Ultimate for free and might be able to use some of its features for work (Mac Office 2007 has gotten me through so far but you never know). Vista works fine in Bootcamp and I installed the latest Bootcamp upgrade as well in order to make sure the latest drivers were on the computer. However, when running the compatibility test the system has scored a 1, largely due to poor graphics performance. I suspect this is probably due to a driver issue with the new graphics card but wanted to have some insight from more experienced users here to see if there was a workaround to improve graphics performance. Any thoughts?
