There was no PTS. There was an "Open Beta". A PTS, "player test server", is a very different thing... That aside, what are you talking about? Poorly implemented? The PC client is actually quite exceptional, it has been coded very, very well and is incredibly well optimized. I have a backup PC with a 5 year old GTX 780 and it runs the game beautifully at 1080p... My main PC has been running the game exceptionally well at 1440p up until this last patch with the random stuttering but they said they have a fix for it.
