The game is so Awesome, and the Multiplayer seems perfect and way improved since the Beta/Demos...
...but, CRYTEK. The Campaign, the most awesome and important part of the game, has VERY serious problem with the framerate. Walking and exploring are ok, but when there are more than 3 enemies on screens everything slows down A LOT, like 15-20fps, and it's really annoying and bad for aiming and playing too.
Please, consider to adjust the 360 Configs with a Patch as soon as possible to keep the framerate stable at least at 25-30fps for the whole game.
It's impossible sometimes playing with this... -_-
P.S.
The game IS installed into the 360 hard-drive while playing...
My Specs:
Xbox 360 Reach Limited - Slim 250GB
HDMI set in 720p from the Dashboard @60Hz
