Global illumination in screenspace: 80fps, noise-free, no reprojection

This is the latest iteration of my SSGI algorithm. Compared to previous version, performance is increased approximately twice(easily runs 80-100fps now on a laptop), flickering artifacts greatly reduced and I have completely ditched temporal reprojection because it’s no longer needed, which means there are no more trails behind moving objects. There is now no more visible noise either. My next video will probably be graphical explanation of how this technique works.
