First thing I noticed is they changed the visuals and audio from the WC 2010 game for the WORSE ! Nooo ... Why ?
Pitch textures are not as detailed as in WC2010. Compare the Bernabeu turf in that game to the one in the Demo.
They have upped the colour & contrast so much that it makes the pitches and kits look too colourful and cartoony, whilst making the edges of the players in wide came look blurry and colour bleeding compared to WC ...
This is why people say PES2011 has more natural lighting as it's not as saturated as FIFA's pallette. You can remedy this somewhat by going into options and taking Contrast down a notch in the Brightness option but then it all looks a little flat and washed out, not a happy medium.
The player models are not as good in my opinion too many models of player have a wide and a thick torso - most footballers are very Lean in real life even skinny at times, a LOT of these player models don't reflect that. Shirts should also be tighter this would help with the look also.
Shoulders of players are sloped, when they should be more square and athletic. The first example of this I noticed was looking at John Terry in replay, who also appears not to have enough of a neck either as do a lot of the player models.
The ball hitting the post now sounds ridiculous and out of place.
Probably the biggest one for me is that they have also removed the beautiful metal "chink" noise of the ball hitting the net that was done to perfection in WC2010 when you scored a goal that was anything stronger than a tap in.
Why didn't they just copy most of the visuals and audio from WC over and then IMPROVE on it not go backwards which is what they have done.
I'm not totally surprised as it is still fresh in my mind last year when I got FIFA 10 home and shockingly discovered that the game largely looked less detailed and not as sharp as FIFA 09 did, again especially apparent in the turf textures and player graphics.
I hope they have/can sort some of this stuff out before the retail version, as it's a shame as they have done some great strides with other things visually this year like player faces (some of the Arsenal Squad is scarily photo realistic)
