It's the drop from 2x to 4x, if you look. As such, the small hit isn't too surprising.
Although,
COJ isn't the title to test to see if AA performance is fixed. Why? Because COJ forces Shader based AA,
so it's doing AA exactly the same as the R6xx in that title.
If we really want to check on the AA/AF hit, you'll want to use a title like Oblivion or UT3. Something that doesn't force specific methods of AA(even Crysis doesn't use traditional AA methods).
