I just tested multitextured terrain with A7.04 in comparison with A6.6...

I used a little 100*100vertex terrain with 512 texture size, and a great one with 500*500vertexes and 2048*2048 texture size. I had no fps changes (constantly 85) with A6.6 at both terrains (even with Normal- and Parallaxmapping applied to the multitextureshader there wasn't a fps change).

Now in A7.04 I get 45 fps with the little one and 23 fps with the large one!

I hope there is something wrong!?
