The 757 flight simulator that I've flown was a full-motion flight simulator at UPS's Louisville training facility. I was helping conduct 6-month certification flights as co-pilot. I would say that if those simulators are good enough for UPS's 757 pilots' recurring training, they're good enough for this Cessna driver to understand that difference between his plane and a 757. Answer: Not that much.
