Ok, after testing XBOX version i tend to agree that this demo is graphically gutted for obvious reasons.
Here is a comparison pic PES14 vs FIFA14 on XBOX360. Please zoom it at max to see the details.
In 1st pic we have cutscene HQ textures (ive imported Steaua Bucharest's HQ homekit for testing purposes), on the 2nd pic we have actual low-res textures that we will get during the match (non-cutscenes).
Now, in 3rd and 4th pic we have HQ textures from Fifa 14, textures that we will get during the match.
It's obvious that Fifa graphics it's better, way better.. i wonder why? Short time for KONAMI to optimise the engine for consoles?
