"As a mid-generation release, we knew that whatever we did needed to require minimal effort from developers," Cerny explains. "We showed Days Gone running on PS4 Pro at the New York event.

In general our target was to keep the work needed for PS4 Pro support to a fraction of a per cent of the overall effort needed to create a game, and I believe we have achieved that target."
The demo stacks up the maximum amount of cars and runs the full AI and physics simulations. It's a highly taxing stress test, used to enforce the strict budgets in Forza Motorsport to ensure the locked 60fps the series is famous for. The ForzaTech port to Scorpio took two days to complete and was fully performant from day one.
