FL Studio Lags and Runs Extremely Slow

FL Studio is one of the best music software solutions that can be used as a Digital Audio Workstation (DAW).

It provides you with the ability to create your own music as well as edit other music files. But sometimes people can be heard complaining about FL Studio’s performance issues. Most of the complaints are centered around the ‘extra sounds’ issue which are very much audible at times. These are mostly glitches or crackles and the sound is often choppy and strange.

There can be two different reasons related to this choppy sound. It could be because of some random plug-in which is behaving like this, or it could be the buffer underrun problem.

To fix the plug-in problem, you need to open the plug-in wrapper processing tab where you can find the Allow threaded processing option. Now deselect this option and check if the problem is solved or not. If the problem persists then you need to select the Use fixed sized buffer option. Once you’ve made these two adjustments, you will stop getting the ‘extra sounds’, in most of the cases.

But if the problem is due to buffer underruns then there are some steps which you need to perform to solve this issue.

  • Navigate to Audio settings and select FL Studio ASIO in the Device dropdown menu
  • Now you need to change the buffer length settings as well
  • Try to get the buffer length to somewhere near 10 ms (which basically means at 441 samples)
  • Make sure that there is little addition in Underruns Count during this process
  • If you find that underruns count stop increasing you can decrease the Buffer Length settings
  • Make sure that the Buffer Length settings value never comes under 10ms else the load on your CPU will increase sharply
  • Remember that Buffer Length and Underruns Count values are inversely proportional to each other
  • For ASIO driver, there can be three different Buffer Length settings
    • 1-4 ms (44-176 samples) which is very good but you don’t need this as it will increase the load on your CPU
    • 5-10 ms (220-440 samples) this is excellent and ideal setting.  We recommend setting it at 10ms
    • 11-20 ms (485-882 samples) which is acceptable and can provide you with a reasonably good sound

With all these steps the choppy sound problem will be solved and you will be able to hear clear music. But if problem persist you can check its memory and CPU optimization section but at your own risk. You can also check different other programs which might cause FL Studio to make these unpleasant sounds. As an example, a program called f.lux that changes the color temperature of screen can cause this issue. If you have installed it, please get rid of it at the earliest.

If the Buffer Length setting is more than 100 ms (4410 samples) and the CPU usage is at 80%, this is basically an indication to upgrade your PC because your system isn’t capable enough to support FL Studio in this case.
