CPU & Memory Panel

The CPU & Memory Panel displays the CPU, polyphony and memory usage for the project.

1. CPU Bar Graph
The CPU Meter shows the approximate percentage of CPU capacity used by the audio generation/mixing processes and correlates with buffer underruns. When this meter nears 100%, the real-time audio will break up and crackle. To increase the refresh rate, Right-click the view to open an options menu.

2. Memory Usage Meter
The Memory meter shows how much of the 2 GB to 4 GB (2000 to 4000, depending on settings) address space allocated to FL Studio remains unused or used (Right-click the panel to change mode between 'Show available' and 'Show used'). If you run out of address space you will experience memory errors such as access violations or buffer overflows.

RAM vs Address space
The amount of 'RAM' you have installed in your PC and the amount of working 'Memory address space' programs running on it have access to are unrelated. Forget how much physical RAM your PC has. All 32-Bit programs can access a maximum of 4 GB 'working memory' and up to 192 Gb for 64 bit programs depending on your version of 64 Bit Windows.

3. CPU Meter Graph
Shows the CPU usage as a running graph, so that you can track changes and observe spikes. Right-click to change the update speed.

4. Polyphony
Shows number of voices (independent sounds) being mixed at the same time.
