Server Error: Client Desynchronization on PC!

I also have this disconnection problem + sound stuttering. I tried fixing the sound problem by deleting 34-40 vpk files and reparing the game, but it does not work. My rig is new i5 4690k + gtx 970, 60 fps, playing in West Europe server with 30-50 ms and still having these problems... I can't play the game but also I can't return it, because I purchased it during the discounts (I think that is the reason, I did not know). Such bulshit madafaka, what kind of "Game of the year" is that...
