Some useful/constructive information and criticism for you:
I can see straight away the improvements over Forza 6 for Xbox one such as the higher frame rate in regards to the rear view mirror, the improved reflections and fidelity of textures, the slight redesign of the tiles system in the home area so kudos for them improvements and many of these where probably planned for Forza 6 but hardware limitations likely got in the way, the game seems well tuned and well programmed and not a barebones port of Forza 6 with new cars so this is also a plus.
Unfortunately you have a way to go before release in my opinion, although my rig has a 4k screen attached to it I usually play racing simulators on my ultrawide monitor set to the cockpit view of the car, Forza has done a very good job with dashboards and the like for a long while and this barely ever gets shown due to the 16:9 aspect ratio, with ultrawide you really appreciate the detail in the dash simply due to it being visible.
Another issue which people on PC will have issues with is the lack of graphics configuration before the first race, I wasn’t able to change any graphics details until half way through the rio race, now for me this wasn’t so much of an issue but if for whatever reason the game is running at a low resolution or maybe too high of a resolution your “player” will lose interest. GRID 2 had this very same issue, they made it so intel IGPU’s ran well with the game but on Nvidia and ATI there was micro stuttering and dropped frames which led to the first race being like hell on earth as the graphics configuration not being accessible until after that race.
Also I was unable to find the menu for changing assist’s, I completed the Rio race and the sebring race and yet still could not find the menu, I hate auto braking assist within forza but it seems to be stuck on.
One last thing, the reflections on the bonnet/hood of the car are great but I don’t really want to see the positioning/placing of the car reflected along with the car and the sky, I can see the car is in 1st position by looking at it, it doesn’t need to be reflected.
Obviously all the above is my opinion and I wish you the best as I will likely pick up the game just hope you understand that to please almost everyone the above is a good start.
Cheers,
