It’s a little bit easier when you have a fixed spec, when you think about Xbox, Xbox One S, and Xbox One X. And you think of the variable specs of the PC space, so you’re taking a fixed-spec PowerPC emulator and then moving it over to run on PC, so there’s a lot of work there,” he explained to PC Gamer.
“The original Xbox, OG Xbox, is a little bit easier, because that was an x86 chip it was running on. Obviously when we think about UWP and the ability for games to run across console and PC, we’re getting closer. I want developers to be able to build portable applications, which is why we’ve been focusing on UWP for games and even apps that want to run on multiple devices.
