RetroArch: Automatic Frame Delay to reduce input latency

Very nice, but there probably shouldn't be a setting for this and it should be the default behavior. I hate it when there are tons of unintelligible knobs on an application if everything could be computed automatically.

Interesting that this is even possible. I would've thought each core would have to implement it independently and many would not ever be compatible with it.

It's so ironic that RetroArch is going through so much trouble to squeeze latency out of video (even running the emulator midway through a frame), yet the Arch Linux package disables the JACK audio backend (the only non-exclusive audio backend that doesn't buffer extra audio on top of the ALSA buffers, alongside ALSA which is buffer-free when talking directly to speakers, and PipeWire which RetroArch doesn't support), and I can't enable JACK in the Flatpak even though it's not explicitly disabled, and RetroArch comes out of the box with a whopping 64 ms of audio latency.
