> So would this be something like rendering a frame of a test scene (utah teapot? real in-game scene?) in various states of rendering (with / without lighting, with / without specular / normals etc), and then making sure they look the same each time? Yes, exactly, it's small test scenes we setup ourselves whenever we add a new rendering feature or fix a rendering bug. Some of them are still not deterministic as we're using Compute Shaders for some stuff which is hard to make deterministic. > You should definitely consider a GDC/etc talk, I imagine it would be an eye opener for a lot of people. We are currently looking for topics. We'll see what comes out of that discussion internally :)
