Dynasty Warriors Gundam: Reborn [BLES02057]

In game FPS could reach 60fps but will drop to 30 when there are lots of enemies, but still playable. Unfortunately, sound is badly desync. Even when the FPS counter hits 60, sound is still desync. Game plays good, if I muted it I wouldn't know the difference. Is it my specs or  can I do something with the settings? I've provided the log.

Right, forgot to add, having same problem with DW Gundam 2, but with DW Gundam (the first) game plays absolutely fine, no desync etc.
