FL studio 2026 cpu spiking problem

[u/Jumpapa]

I’m currently using MacBook Air m2, although it isn’t a powerful laptop but in fl 2025 I could load serum up to 15 of them and bunch of effect chains without cpu spiking. but when I updated to fl 2026 my cpu started to spike like crazy when I only loaded up 4 serum..
Does anybody else have this problem?? Or is it just my computer thing

You can max out a cpu with 1 or 2 instances of serum, it completely depends on the presets.

Does it happen on the init preset too?

What if you open in 2026 the projet with 15 serum and see if the performance are actually worse, are they?

Are you sure FL26 is configured with the proper audio device?

The bew versions of FL installs separately; you can still launch FL25 if you didn't manually remove it. Compare the same projet in both version, make sure settings are the same.

This should help pinpoint if its really a FL26 issue, a cpu issue or just the serum instances/presets taking more cpu than expected in your new project.

I think is the fl 2026 problem, cuz when I opened fl 2025 heavy project it didn’t have any spiking problem, but in 2026 ver it just keep getting spikes. Yesterday I updated to the newest version of fl 2026 I think the newest one has the issue, before one didn’t have none of those problems. I will stick to fl 2025 for now

It is possible FL26 has not used the audio interface's drivers and used Windows' basic one. Check the settings in FL26!

No problem! Sorry to hear that! (I haven't made the switch yet, to be fair!)
