"Only" 30fps or downsize to 1080p... funny how that is always the main criticism to Driveclub ("it's 30fps!") but now it seems to be "only" a minor thing.
It's not "the only difference", there's no shadow casting in Performance mode, which is already an X version exclusive, so it's only on the X in the 30fps mode:
But guess who does dynamic shadows with 1.8Tflops:
For both cars:
And track side elements:
And this is a thing that even on PC Ultra doesn't look good on FH4 due to its razor sharp shadows:
FH4 Motion Blur is a whole different quality from one mode to the other:
And according to Digital Foundry, the X version "notably gets higher quality car interiors" than the regular version.
It's all here:

And all this running on 3x more powerful hardware (6 Tflops XB1X vs 1.8 Tflops PS4).
+ important differences with the base version:
I was talking about what makes for realism, mainly lighting and effects. That's where the core of Driveclub shines (yeh, yeh, sometimes it fails too) more than the core of Forza, despite its shortcomings in resolution, bad AA, etc.
