The frame rate is absolutely awful at times on 360 and it along with the texture problems have seriously hindered my repeat plays of the game. Its simply unacceptable regardless of how great the rest of the game is and it is very noticeable without going looking for it. If it is still there in the 2nd game I wont be buying it for 360.
I honestly turned it off yesterday because it was running like wall paper paste, I really can't see how you wouldn't notice it. I can't actually think of a game on the system with a less stable framerate that I've played myself.
Almost all of them. Yesterday it was with a new character I had started on Eden Prime fighting a few Geth drones, it slowed so much I gave up.
