FYI, there is no dx9 compatibility option in dx11. it is a superset of dx10, meaning that dx10 hardware can use the dx10 base of the engine and won't implement the extra dx11 features.
currently you write a dx9 version of a game, and then write a separate version for dx10. there is some overlap, but they are fundamentally different. dx11 is better thought of as dx10+. the card/hardware can execute the 10code and ignores the +code. there is no option to convert it to dx9.

Then why does it say

Direct3D 11 on Downlevel Hardware

Direct3D 11 is designed to support both new and existing hardware, from DirectX 9 to DirectX 11, as shown in the diagram below.

read the paper. d3d10level9 primarily allows you to use dx10+ hardware on dx9 driver.

also if it makes a function call that wasn't enabled on dx9 it wont work. you have to rewrite the function.

This is dishonest and simply done to trick poeple into spending more money IMO. It one of the reasons I hope that Fermi is a complete and total failure and Nvidia takes a huge hit. If they can convince people they make the fastest card out there, then the masses feel that their whole line is better.

On the other hand, if AMD stays the underdog but able to run in the black they can continue to provide users with the best prices/performance parts on the market for the forseeable future. I remember the Athlon days when AMD was smoking Intel parts for about 50% the cost because they had to price competetively... would love to have those days back.
