Less pop up from far away distance in front and in the rear view mirror makes sense, as this is help with the extra power from the Pro.
And that should be reflected on screen and inside the PSVR2... It would be good to see a side by side to be exactly sure...
As for the resolution being better inside the PSVR2 I am highly skeptical right now.
The video shown by
@TheNormsk is what is displayed on the TV screen and thus no representative of what one would see inside the VR2 set....
The resolution on the TV is different from the resolution inside the VR2 set, therefore I don't think this confirm anything...
But please prove me wrong ...
