I've been playing this game for about an hour at a time because I simply cannot play any longer. My eyes become really sore and my head starts spinning literally as soon as I get in game. I see many other people are also experiencing motion sickness. In order to combat this the devs have removed motion blur, which is a good start, but had no effect on me. The head bobbing in this game is completely unnatural and causes all of my motion sickness. Other games have had similar problems where head bobbing causes the sickness, so this should be removed from the game completely. It detracts from the experience in every game I have ever played, and it makes this one near unplayable. The mouse acceleration should also be removed, I have no idea why this would ever be added to a game with keyboard and mouse.
