I already saw that but I don't think it's true, Gameloft guys are just a bunch of liars, I went to their forum and they're most of the time ignoring the Tegra 3 related complaints or answering the exact same way they answered to you (it's like if they're all doing a ctrl+c-ctrl+v)
And, considering the way Asphalt 7 and The Amazing Spider Man (this game doesn't even support post-treatment for Tegra 3!) were optimised for Tegra 3 and considering that Gameloft had time to do the work before releasing these apps, I guess that nVidia didn't pay the extra money Samsung paid to get properly optimised apps...
Even The Dark Knight Rises was not THAT well optimised...
Considering all that I would assume that Gameloft developpers don't know their work or what "optimising" means but considering how Gameloft games work on SGS2 and SGS3 I think that Samsung just paid some money...
