PANELS

CPU Panel

The CPU panel displays the polyphony and CPU usage of the project.

    1. CPU Bar Graph - The CPU Meter shows the approximate percentage of CPU capacity used by the audio generation/mixing processes while playing the current project. This meter does not take into account any Graphical User Interface overhead from either FL Studio or plugins. For a more complete estimate of processor load, use the Windows Task Manager (press Ctrl+Alt+Del and select the Performance tab). To increase the refresh rate, right-click the view to open an options menu. For tips on reducing CPU usage see the Troubleshooting section.
    2. RAM Usage Meter - Shows the RAM address space available. Forget, for the moment, how much physical RAM you have. All 32-bit applications can address (see) a maximum of 2GB memory (ignoring programming trickery that can sometimes allow more). Remember address space is not physical RAM. Each 32-bit application running on your machine has its own 2GB of address space to play with. The RAM meter shows how much of the 2GB address space is unused by FL Studio. If you run out of address space you will get memory errors such as access violations or buffer overflows. So how about your physical RAM? If FL Studio needs to use more than the total physical RAM available, Windows will make up the difference by using 'virtual RAM', swapping data to and from your hard drive, to simulate physical RAM. Large amounts of physical RAM are desirable because all programs run faster when working with physical, rather than virtual, RAM. In particular, FL Studio is less likely to experience buffer underruns if all the data it needs is held in physical RAM. If you want to know how much physical RAM you are using, press (Ctrl+Alt+Delete) to open the Windows Task Manager, and select the Performance tab.
    3. CPU Meter Graph - Shows the CPU usage as a running graph, so that you can track changes and observe spikes.
    4. Polyphony - Shows number of voices (independent sounds) being mixed at the same time.

Note that TS404 channels are not counted when displaying the polyphony.
