Well, installing that demo and getting it to work sure was problematic for me!
But I can say that it is simply fantastic! My PC runs the game veeeery smoothly!!
And I don't have the best pc: Intel Celeron 2.4 Ghz processor, 384 MB of RAM, and an ATI 9250 Graphics card.
Yes, my PC is OLD, and yet i can play this demo with fantastic results! So if your PC is better or like mine, rest assured, you can run it!
IMO, the gameplay is very realistic, yet I do agree, the cutscenes and things like shoothing are VERY fast. I played Brazil v Portugal, and C.Ronaldo took a shot on goal and the ball just whizzed through the air, I could barely see it!
However, for me, my issue is with graphics. While this may be a next-gen game, my graphics card cannot take full advantage. My ATI 9250 unfortunately only has pixel shader 1.1, so I am FORCED to keep graphics at low settings. While the players still look great, things like crowds, kit wrinkles, etc, I cannot see. But the good news is that I might be getting a next-gen console or a new PC this winter (I havent decided which, anyone have any ideas?)
Lastly, my only peeve is that Konami does a VERY bad job in converting console games for PC...but oh well.
Point is, the demo is great! The graphics are SUPERB (not mine though) and the gameplay HAS to be slower. Like you guys said, it feels like an arcade game, and that is UNACCEPTABLE for Konami.
