Ar Tonelico Qoga : Knell of Ar Ciel [BLES01102]

Is there actually a performance difference at different resolutions? I mean yes 480p is maybe a few frames faster than 1080p but it doesn't seem to matter much for me.

FPS differs about 2-2.5 times for me if I compare 720x576 and 1280x720.

Hmm... Well even at 720x576 the game seems slower for you than it is for me in 1280x720 on an i7-2670qm in a laptop. Maybe it is expected with such a slow old AMD CPU. But I'll actually ask graphics developer kd-11 about this.

...
It is epected I think, but also video recording eats about half FPS, without it FPS at 720x576 is 45-60. Anyway I don't expect my current PC ever actually emulate PS3.

What I was surprised about was that dramatic rise of FPS (from 15-20 to 45-60) gave almost no improvement in most laggy places of intro, while FPS-count clearly shows 40+ in actuallity it is as laggy as before.

The game likely does some kind of internal frame skipping on it. Think that the video is 24 fps but it outputs at 60 fps. Something like that is going wrong here.
