iv got the ps2 one it runs fine.
Although the enemy generals vanish on some missions for a few second then come back again, but thats happend on all the warriors games. thought they might have fixed it by now

actually it happens on most dynasty warriors game. disspearing enemy's around you happens all the time. so the game gets a higher framerate and runs smoother.
most consoles cant handle so many enemy's.
and because the detail goes up all the time and how many polycons there are, thats why it stays even for the xbox360 and stuff.
