Rewind capture introduces audio skips #49

Closed mathieulh closed 3 years ago

mathieulh commented 4 years ago

Regression: Between the revision 20.01.19 and the rewind version (available on discord), an issue has been introduced, when playing the "FFVIA SNES color+Sound-Opera+CAPS" restoration hack, audio skips happen (very noticeable while playing the intro) on the rewind version which do not occur on the version from 20.01.19

UPDATE: This only appears to occur when rewind capture is on.

Rewind capture currently has 5ms pause per second, which may lead to slight stuttering. This can be further reduced by block copies and parallel read/write.

Confirmed, with a different game (Piglet’s Big Game), but also seeing a steady stream of visual glitches as well. Happens throughout the play, across all areas. Turning off rewind fixes the issue.

Rewind capturing has some drawbacks mentioned in the readme, that cannot be avoided. So there is no point in keeping this issue open, as it will not change.
