Ar Tonelico Qoga : Knell of Ar Ciel [BLES01102]

Tested one of the latest builds today with 720x576 resoluton. FPS was even 60 sometimes (OBS drops FPS about twice, so it cannot be seen in video below).

Surprisingly some obvious lags in Intro do not cause FPS drop, as if the issue is not in video rendering but somewhere else.

Also, some graphic glitches, but they are not primary issue. Anyway, it seems, there is long way ahead in optimization before it would work at at least 720p and stable 30 FPS without lags.

However progress that was made since half a year ago (when I tested it last time) is really great.

And no surprice that my AMD processor works like... well it does not work good enough.

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.

Same result here on 96b5e9dd:

On 720*480, counter stays at 60 FPS all the time during the videos but they run as utterly shit as always.

May be playable as of this PR but I saw some strange crashes earlier. Could just have been settings or on my end (ASMJIT, LLVM, OpenGL). Someone confirm?

[Captain_Nemo]

Save game works now (only 1 save slot, though).

As for crashes I guess it should be tested in somewhat long play, at least several hours, cannot perform it with my low-end CPU (playing like this is a sort of torture).

Also, from what I see, there are much less graphic glitches with Vulkan, but FPS is greatly also lower.

Maybe leave the game running for an hour or two and see if it crashes/hangs.
