So, a friend of mine (Swedish one, if this makes any difference) has got a problem with ETW sound. In the intro movies and in-game ones his sound stutters and lags. He played with the sound settings in-game with no result, however, the lag appears only in ETW, not in other games. His computer is new, so I think his driver might be up to date, too. Have you got any idea of what may be causing this and how to fix it? Thx.
