I doubt that this is a technique for real-time applications. They don't say anything about that on the website.

True, especially because they would probably talk about things like temporal coherency if it were meant to be applied to video/game feeds.

This seems more in line with potential real-time applications, though it is still a lot slower than DLSS: https://dl.acm.org/doi/10.1145/3641519.3657439
