In a recent interview with finder.com.au, Quake Champions Creative Director Tim Willits revealed that the game would not be using their Id Tech 6 game engine.
“We had such success with Vulkan and Doom that Robert Duffy, our chief technology officer, was like, “alright guys, this worked out well for us. So we need to do it [with Quake].” But we still have to look at it, because Quake Champions’ technology is part id tech, but also part Saber tech. It is not on Id Tech 6 [game engine]. If it was, it would be all good with Vulkan and we would be happy.”
