[Playable] Hero of Sparta

[XperiaPLAYer27]

Hi, i have some graphics problems and, its a bit slow on my xperia play(Android GB 2.3.4).
It goes about 15-42 FPS(Almost allways about 16-17 FPS).
I post screenshots, look at left down corner in gameplay, there is little rectangle with transparent gameplay in it, it looks like little transparent "twin" of normal gameplay.
May theese problems be caused because it is CSO?

/Sorry if my english is bad

See down left corner
