Then you didn't know what you were doing when installing OS on said friend's computer. But I'll give you the opportunity to prove this so-called 3x performance. Choose your benchmark and run it. I will run the same on my Vista machine. We'll post screenshots here.

Not a fair contest.

You are running a overclocked hi end C2D with 4GB RAM.
How is that fair compaired to a single core Athlon with a GeForce FX?

It hardly is.

Seriously make sure computers are evenly specced before testing Vista performance against other OSes.

Other than that it would of course be because its handling more complex graphics.

.....

Now you let the cat out of the bag....

Please, post SPECIFIC examples of HOW DX10 is better to DX9 OR OpenGL 2.1 WITH GL extensions.

Also, post a detailed description of what benefits DX10 offers to the average graphics developer.

Thank you.
