I actually preferred GT5's visuals. It seemed less blurry. Also I noticed quite a lot of framerate drops. I didn't play it longer than about an hour, but the whole thing felt a step backwards from GT5. And the engine sounds sound like a Scooter 50cc. Im not going to make any comparisons to Forza 5 because that's not remotely fair. But compared to last generation sim games, I thought GT6 was pretty bad.
