Yeah, it's absolutely mind blowing. My last involvement with graphics programming was the 90s demoscene, and fill-rate was a massive constraint on doing cool things. Doing the amount of math these modern engines do per frame, let alone multiple times per pixel, would have been unimaginable. It's amazing and cool how much GPUs have changed all that, and the techniques are so different and constrained in such different ways.
