From our perspective, what's fascinating is that so much has moved on since we saw a quick port of
FM6-era technology running on prototype Xbox One X hardware, and as good as it was, you could see that anisotropic filtering wasn't as high as it could have been, while those hard edges did exhibit a touch of aliasing and shimmer in motion.
These artefacts are cleaned up in FM7, and the clarity of the image is quite breathtaking. The visuals pop, and sub-pixel elements - especially noticeable on the player car model and far-off environment detail - resolves with minimal pixel break-up. To get that level of fidelity at native 4K is hugely gratifying from a visual perspective.
But just as impressive is the implementation of full dynamic lighting, allowing for gradual time of day transitions as well as a full-on weather system - all real-time now, as opposed to FM6's baked, static equivalents [
UPDATE 17/6/17 2:20pm: we'll need to look at our captures more closely, but transitioning between multiple baked lighting models may be how Turn 10 has achieved this - it's an approach most recently seen in Horizon Zero Dawn]. During our Turn 10 visit, we could see how the developers could tweak lighting and weather on the fly during runtime, as easily as a movie colourist grades footage. The Nurburgring is the host circuit for demonstrating both technologies in the E3 demo, where a grey, overcast day turns into a fierce thunderstorm, before subsiding into a clear skies sunset, the track illuminated by floodlights. Everything we'd want from dynamic weather is here in terms of effects, but also with water accumulation and some beautiful reflections in the puddles - check out the end of the gameplay footage to see this in full effect.
