I read this as they’re even generating the frames with AI:

The tech demo is part of Microsoft’s Copilot for Gaming push, and features an AI-generated replica of Quake II that is playable in a browser. The Quake II level is very basic and includes blurry enemies and interactions, and Microsoft is limiting the amount of time you can even play this tech demo

While Microsoft originally demonstrated its Muse AI model at 10fps and a 300 x 180 resolution, this latest demo runs at a playable frame rate and at a slightly higher resolution of 640 x 360. It’s still a very limited experience though, and more of hint at what might be possible in the future.
