文章: Jonas Maki – Gamereactor.cnIf you’re a PC gamer, we think just hearing about Denuvo will give you chills. It’s no secret that notorious anti-piracy software is quite effective, but unfortunately, this often comes at the expense of honest gamers who are also negatively affected. So we’re assuming that few of you will have heard that Starbreeze has decided to remove Denuvo from their upcoming Payday 3, which is launching on September 21st. There’s no explanation why they did this, but a reasonable guess is that they noticed the game suffered from it in some way – and we’re not complaining one bit.
