Thanks all for the replies, that's true the progress further in the game makes I get the slowdown. but it's pretty strange, no matter if I am using internal resolution 640x528 native, with no AA and AF 1 or 2560x2112 + AA 16xq AF 16 the FPS will be stuck at 25-26 then I suspect this is hold by the GPU, if so, why it still so slow? I suspect this is a bug that the developers has not find the way to fix
