Part of the reason why CD Projekt Red has been able to nearly max out the power of the new machines is because the studio decided to skip Xbox 360 and PlayStation 3 more than two years ago.
"So we've spent a lot of time with these machines, and it's been a great experience across all three platforms. On the old platforms, namely the Xbox 360 and PS3, we probably would have had to sacrifice nearly half of our vision," Iwinski said.
Earlier this week, Iwinski said releasing an uncompromised version of The Witcher 3 on Xbox 360 or PS3 would be "impossible."
