Started playing a couple of weeks ago and the game set me up on ultra. Everything ran perfectly and I really enjoyed playing. The other day I signed off as normal but then when I signed back in the next day I had a real problem the game became unplayable. If I stay still or move in a straight line everything looks good. If I then look up/down or left/right then everything freezes for a split second then jerks to the new view.
I’ve tested with Fullscreen, Windowed and Windowed (fullscreen), make no difference.
I tried setting it down as far as Low, no differernce. Thought it might be a problem with my mouse, nope same with different ones. I have no problems with the internet or with any other program that uses the internet.

Hope someone can point me to a solution. Otherwise I’ll have to abandon this game. I'm on the EU server.
