#2. And once that happens, where does that nice glow come from? Is everything being rendered by the GPU to a texture on the GPU, then having that texture rendered back onto the final scene, with a shader applying the glow to that texture?
#3. The nice grainy effect, along with the analog signal noise degradation that is applied periodically, is that just something applied to the whole scene after the fact? If so, I'm guessing this means that the whole scene is rendered to a texture so it can be post-processed and rendered out to the backbuffer as a texture on a quad?
Very curious about all of this, given that it's an area I've started learning. He who asks questions learns faster
