After reading the article from NEWS.com.
It shows that Snow Leopard beat Windows 7 straight in general performance areas.
However the following report showing that Windows 7 beat Snow Leopard in 3D Rendering
Windows 7 3D rending is far more faster than Mac OS in such scenario. I think it give a boost for gaming industry in Windows platform.
Anyway it doesn’t mean you can start convince your Mac user friend to use Windows for their production. I very sure they WOULDN’T 🙂
