mac 3d game issue:if I run fm in windows xp in a mac is this going to improve the 3d?

I have a problem with my new aluminium macbook.

The 3-d game graphics are not very good compared to the graphics I have seen in a PC friend last week so the game in mac is less enjoyable tha in pc.(I have 9.2 patch installed and high qulity graphics detected)

I know about the option of installing windows xp in my mac to have both systems

The question is:

Does the FM 3-d graphics runs any better via PC if I install windows xp and lunch it this way??

Is this possible or it´s a hardware problem???

Will re-post my answer in the other thread. No need for a new one.
