working great for me on HTC One X FF9 has never been so playable with OpenGL i made a little video to show these are some of the biggest moves in the game so the slowdowns are as bad as they are ever going to be
i run it on the one X which has the same Tegra 3 SOC and playing Final fantasy 9 runs at about 140-160 FPS normal & 80-100 in battle scenes with OpenGL (better graphics) i get 100-140 normal & 45-80 in battle
