Other details

This also affects Fairy Fencer F [NPJB90640] as well

@kd-11 Retested this game again and #14907 partially solves the issue seems to only work if wcb and rcb are both turned on. rcb only gives you the same behavior.

Note, that using buffers comes with a performance penalty and sometimes give strange behavior like the game just randomly ran a 6fps when wcb or rcb were enabled turning it off and on again resolved the behavior but odd nevertheless.

Also, Fairy Fencer F had similar behavior but was far more destructive looking like memory corruption and crashing but the latter seems to be fixed with #14907 might have to make a separate issue thought properly affects both games to some extent.

Any issues left when using RCB+WCB? If any standard combination (outside debug tab) fixes the problem, then it can be considered solved. As I noted in #14907, there is no way to avoid the leaks without both RCB+WCB (or RDB+WDB in some games) enabled at the same time.

I would need to test the game for longer. There is a performance hit that makes the visual novel + tutorial aspect close to unplayable (stutters to 6fps to under 1 fps for a few seconds. also happens with the default setting but it less severe stutters but drops to 20 fps)

So even if it is been fixed I don't know if I can call it solved completely.

Also Fairy Fencer F has a weird issue with graphical issues the longer you play the game. so not sure if affect this game that uses the same engine.

Do the FFF bugs happen with a strict setup? (WCB+WDB+RCB+RDB+CPU blit)

[Triticum0]

Will test now but seems to happen with the default settings

[Triticum0]

Yes it does. Also the graphical issue don't seem to show up in Rsx captute

Ok, got it. If NeptuneV bugs are not present when using WCB+RCB, close this ticket and open one for FFF. There is nothing that can be done for performance at the moment without some other architectural problems getting sorted first which will take a long time.

[Triticum0]

Thank you for the help will reopen or create a new issue if I run it into any other issues when retesting Ultra Dimension Neptune later on.

Also with the performance issue I move the game ingame as it was previously mark as playable when WCB andn RCB where disabled

[Triticum0]

Do some more testing and didn't have any graphical issues will update the wiki now.
