Left Ctrl / Right Alt key 'stuck' - SOLVED - posted in Ask for Help: Hello all,So, I just spend about two hours struggling with a keyboard problem and I _finally_ solved it. With this set to 0 the game doesn't wait until everything is loaded to throw you off the loading screen making it quicker, but a side effect of this is that it can cause some strange behavior with collision making invisible walls appear on really slow pcs. Mass effect 3 gets stuck at checking for downloadable content screen at the start of the game.
