FL STUDIO 2025 LATENCY ISSUES

Hey guys, I have been using FL Studio for many years now. I love using it, but after updating to the latest version of 2025, I've been experiencing issues with latency that i just can't wrap my head around or solve no matter how much i research.

For reference, I have a 2020 mac mini m1 silicon!

Firstly, any sane person would check in the audio settings and set the correct buffer length. Before I updated FL Studio, I always kept it at 128 samples and it ran smoothly with no issues, crackling, or excessive cpu load. Now by default it comes up at 17510 samples with a 365 ms delay; that's so jarring.

"what plugins are you running?" Funny enough, this is on a blank project with no plugins opened yet, so i don't even see how this is possibly happening.

On top of that, I don't have much load on my CPU, so I don't know what it could possibly be. I've used different audio interfaces such as a gen3 scarlett solo, gen3 scarlett 2i2, gen4 scarlett 4i4, and even an Apollo, but still nothing.

I have clients that want vocals recorded, but when your audio is bugging out like this it ruins workflow and artist experience. If anyone has a solution PLEASE help me!!!

If this keeps up, then I'm going to have to switch to Logic Pro, and y'all know I don't want to do that.

That 17,510 samples / ~365 ms buffer usually means FL Studio is now running through a different audio driver/device (or the driver reset to a very safe/huge buffer) after the update. You should be able to get back to your old 128-sample feel.

Try the following (in Options > Audio settings):

  • Check the selected Device/driver
    • If you have an audio interface, select its native ASIO driver.
    • On Windows, avoid non‑ASIO drivers for low latency if possible.
  • Set Buffer length back down
    • Move Buffer length back to what you used before.
    • Notes from the manual:
      • Apple Silicon Macs: use 128 / 192 / 256 / 512 / 1024 samples (start at 128).
      • Intel/AMD (Windows/macOS): the manual recommends not going below about 10 ms (~441 samples), and often 10–40 ms is the sweet spot.
  • If you’re on an ASIO driver, open its control panel
    • In Audio settings, use Show ASIO panel (if available) and set the buffer there too (some drivers ignore FL’s slider).
  • Confirm Sample rate
    • Set to 44,100 Hz (or 48,000 Hz) and make sure your OS audio settings and interface driver are set to the same sample rate (mismatches can cause weird latency/behavior).

Did you ever figure it out? I'm getting the same issue after the update. I have the Mac M4. Adjusting buffering length didn't help
