The texture of the rocks and trees. Also the light reflection on the car. It's noticeable but not mind blowing 

For anyone interested, there is an hour of the 360's versions here. https://www.youtube.com/watch?v=kWU7OFijEzI

I clicked around it, looks pretty good. Its bland compared to the X1 version, but the game is intact.

Honestly both version are really similar on those low res gifs.

Forza 2 on XB1 really looks like an up-resed X360 version.

Sumo are great devs. Might pick it up on 360 bef9re finally putting the console dowm for good

The old Xbox 360 still amazes after all these years, Wow!

Amazing what they can do with hardware that's almost a decade old. The X1 clearly looks better (obviously) but damn.

Wouldn't call it a next-gen difference but there is definitely a noticeable improvement.

I played the demo extensively. Visually the game is stunning. There's no way the 360 version gets anywhere close to what I played. The things that stood out to me were the lighting. It's really impressive. All light sources are dynamic, every lamp, headlight etc. The skys always look different due to how well playground have implemented this particle light system. The sunrises and sunsets and actual colour of the sky is so good.

The weather is great to in the atmosphere. At night the other headlights refract through the droplets on the windscreen. But I have one complaint. The spray of the cars looks so out of place. It looks crap against everything else. Why? Everything else in the game is the best I've seen this gen so far with the pad in my hand. The spray is so disappointing.

lol, you need direct feed screenshots for proper comparions, not screencaps from YouTube videos...

But there's no doubt that the X1 version looks significantly better, especially the lighting system.

Gotta say the 360 versions looks awesome, but there is a clear difference. People only having 360´s will get a great game either way.
