Optimizing CPU and memory usage

This section contains tips that will help you reduce CPU and memory usage in your projects.

• Try to reduce the number of used TS-404 and external plugin generators. They all sound splendid, but also require much CPU power.
• Try to reduce the number of effects you use in your songs. Now you can have one effect "weighted" in several FX tracks (see FX send tracks in Mixer window).
• Try to use Smart Disable whenever possible (see Mixer window). If there are many effects you don't use constantly during your song, this feature will decrease CPU usage significantly.
• Try to reduce the number of delay echoes (see Function Channel Settings) because they are actually retriggered samples (it is not a global delay line), so they increase the polyphony. In 99% of all cases Fruity Delay effect does the same job without using much CPU.
• You can use the maximum polyphony setting to reduce the maximum polyphony of channels (see Miscellaneous Channel Settings). This often reduces dramatically CPU usage in complex melodies. You can still set FL Studio to ignore the maximum polyphony settings when exporting to wave/mp3 file (see Exporting to WAV/MP3/MIDI).
• Trim (with any wave editor) the remaining silence or quasi-silence in your samples not to have it mixed (you don't hear it but it takes valuable CPU time). Any remaining ZERO silence is automatically removed within FL Studio, but nothing more.
• Echo Delay will not trigger echoes (thus freeing CPU resources), if feedback is set to minimum (see Function Channel Settings).
• Do not enable the MIDI output (see Enable MIDI Output in Options menu) if you don't plan to use it, because it lowers the performance of FL Studio.
