Ok, this is a personal observation regarding a DX11 game called Dirt 2. On the 4870 (DX9) the frame rates were higher then in DX11 using a 5870 (edit: noticeable from inside and outside the trailer only). There's no denying that. However, the image in DX11 is noticeably sharper without looking hard. The colors are a tad better but not as noticeable at first. As for the tessellations on the people, flags and water it's not noticeable per say. For example, you won't see waves in the water unless you are already behind another car. The people do look better but again you have to be actually looking at them.
What I noticed the most is how sharper the game looked and the colors did look better. If I am not mistaken this maybe do to the post processing techniques between DX11 and DX9. DX11 can post process at full resolution without the same performance penalty of DX9 (only 1/4 of that) which would provide a better image quality. The High Definition Ambient Occlusion along with DX11's HDR is full floating point color depth of R16G16B16A16 vs DX9 color depth of R8G8B8A8 may have contributed to why the colors are better.
The other noticeable thing is how lag free racing is now. Although the frame rates under DX11 are lower then with my 4870 using DX9 the input response time was a whole lot quicker. Thus the car responses a whole lot better now. I honestly can't say why that is but it's apparent and immediately noticeable. Also, the game is much smoother then with DX11 then with just DX9.
Examples:
DX9 using 4870
DX11 using 5870
