about your comments:
graffiti:
you are wrong on your graffiti comment, I wonder why? because forza has more texured road, that's gotta be "imagined", right?
well in fact road graffiti in forza is LESS than the real road, I remember Turn10 saying that they went and removed every single piece of graffiti they scanned that was painted on the real road that was -or could be viewed as- offensive. (you know, dicks, swearing, offensive symbols etc)
so, there you go about your "invented graffiti" lol
trees:
many trees in GTS have this very disturbing LOD and shade change as you approach, like shape-shifting. forza backdrops are clear like a painting.
did you miss that?
light:
also lighting runtime is more flat in gts, on forza you have those patches of light etc small details. I guess you missed that too.
compression on GTS youtbe video, but no compression on forza other half of screen?
I won't even answer that. in fact it seems that forza footage was synced on gts footage, which was the base footage.
You might have to consider at some point, that forza video is also compressed and looks clearer runtime.
Plus your pics are of a different car/dashboard, I guess you missed that too.
also, I have to notice that 3rd person view, GTS car shades on road is pretty low texture-blocky, spoils the view.
car model has less jaggies though, and road edges sometimes smoother too than f6
