After reports of possible frame tearing of the ps3 version of PES 2008 IGN UK has also come up with notable problems of the x360 version.
This is what IGN UK noted in its review of the x360 version of PES 2008:-
"Seabass and his team have come good, then. Next-gen Pro Evolution Soccer 2008 captures the essence of the original games perfectly, gives it an HD injection and takes the AI to the next level. It's by no means perfect, though: compared to the PS3 version it runs more smoothly with far fewer drops in frame rate, but on the flip side there appears to be a weird distance filter which overlays the pitch, so the grass near the camera looks sharp, halfway up it's a bit more blurred and in the distance it's fuzzy. Normally that wouldn't be a problem but the depth changes are fairly visible – two curved lines arc across the screen - especially on an HD TV, and while it won't ruin your enjoyment of the game it does look a little odd."
