I can understand your point; but I had a while back tried installing on Windows 7 with the same issue; and Windows 8 actually seems to have huge under the hood improvements which seem to make performance in most areas better than Windows 7. (Despite some obvious buffs in the area of user experience; 8 Seems to be a huge improvement over 7 strictly from a performance standpoint.)
I am open to further testing or reporting of any data needed to resolve this.
I don't have my laptop handy, but check the Nvidia control panel and see if there is an option to select the Nvidia card for your machine. I have a AlienWare machine and I can change between the Intel onboard and the Nvidia card.
I get completely different Windows performance results switching between the two graphics cards on my machine.
