At 1 FPS this isn't quite real time enough to be useful for real time use cases, but I can see how a realtime stable diffusion would be a fun tool to use when producing for live events.
Corridor Digital (YouTube channel) recently produced a video using almost exclusively img2img stable diffusion to redraw scenes into a cartoon/anime style.
I wonder if something like Redream could have sped up the production process rather than batch img2img.
The base SD model run okay on CPU, and reasonably fast with intels MKL backend. But getting the whole auromatic1111 package to run on CPU seems to be a bit more complicated
My first thought as soon as I saw the title. It is the name of a Dreamcast emulator, however; as far as I know it is mainly free and offers some sort of cheap upgrade for certain features.
