60 fps patch causes some combat sound effects to be doubled

[Crowley9]

While running the game in 60 fps some sound effects in combat are played a second time with a slight delay. These include the whooshing sound when swinging a melee weapon and the click when reloading the handgun. This issue is absent when running the game in 30 fps. I am playing with the 1.2 version.

Good catch, and I'm fairly sure I know what this is.

The game's animations tick at 30 fps internally. With the 60 FPS patch the logic runs twice per animation frame, so every animation frame gets "visited" twice. Anything that fires on "current frame == N" (melee swing whoosh, reload click) fires twice, one game update apart - that's your slight delay, about 16 ms. Sounds that are triggered by a state change rather than a frame number don't double, which is why it's only some of them.

Fix is on the game-code side: dedupe the trigger so the same sound from the same actor can't fire twice within an animation frame. It's on the list for the next update. If you notice other doubled sounds beyond the swing and the reload, drop them here - the more trigger sites I can confirm, the better.
