Is anyone else getting these? I'm using an HDMI cable, 1080P, and xbox pro, it seems like in multiplayer that the game is not fluid AT ALL, it seems at times I will get around 16 frames per second, and a max of around 25, it is terrible, and in singleplayer its even worse, when I aim down my sights and start shooting it seems like the framerate is lower than 15! My computer runs Crysis 2 better than this! Anyone else having these problems?
