This past Sunday Microsoft and developer Turn 10 finally provided a look at the new Forza Motorsport and did a bit of boasting about the game's features, including real-time on-track ray tracing and a 48x improvement in the series’ physics simulation. That said, the trailer was arguably a bit deceptive as well, as it claimed the Forza footage was running on Xbox Series X. Microsoft has since clarified that the footage was running on PC, but claim the Xbox Series X ought to offer a similar visual experience.

We incorrectly stated that the Forza Motorsport demo was captured in-game on Xbox Series X. The demo was captured in-game on PC and also tested on Xbox Series X for the same visual quality output.
