I know that question was aimed at puppet but I've tried both and neither made any difference. I'm only guessing it's the view height though as that's really the only major difference in the 2 modes (apart from the obvious!) all settings are the same and as I say I've played games with much worse head bob so ruling that outDo you run the game full screen windowed? I did I changed that to just full screen and was able to play a load of squad games in fpp without any issues whereas previously I felt really wierd after a single game.
