In the example above, I’m merely using a quarter of a single GB, yet my CPU usage is clocked out at full capacity. This is the most common scenario when dealing with optimization issues. The quick fix for this is changing the buffer length on your selected soundcard. You can find this option by going to the main tool bar and selecting “Options” and clicking “Audio Settings.” There, you’ll see your Input/Output Device. In the past, I would recommend downloading and installing the ASIO4ALL driver, which is also an option when you install FL Studio. Recently, FL Studio has created their own driver called FL Studio ASIO, which I found performs on par, if not better than the ASIO4ALL driver. By switching to the FL Studio ASIO driver and increasing the buffer length to 2048, I was able to dramatically decrease the CPU usage. This is the same project as before, just with the increased buffer size. One thing to note is that when you increase the buffer size, you increase the latency in the project. So if you’re using a midi controller, you’ll notice that when you move a control, these will respond slower than before with the lower buffer size. I personally will use lower buffer sizes early on when I’m using my midi keyboard. That allows me to have a more natural performance when I use my keys to play my VSTi’s. After I record my midi, I’ll then increase my buffer size (if needed) to do my mixing as I add more CPU intensive plugins.Īnother workaround is to convert your midi to audio. This frees up your CPU from having to operate your VSTi’s when your playback your project. In FL Studio 20, there are more options than ever to convert to audio. Solo your midi and hit CTRL+ R to Export to WAV.Click the white dot, disk recording icon, on your FX insert your channel is linked to, which will turn the dot red, and hit ALT+R to render to WAV.Right click your pattern in the pattern selector on the playlist and select either “Quick Render,” “Render,” or “Render and Replace.”Īnother option that can hinder your CPU performance is your sample rate. ![]() I recommend keeping your project at 44100 because this is the same quality that your final audio will be rendered to in the first place. You’ll barely hear a difference, if at all, when increasing this, so it’s not worth the CPU usage. You’ll notice that some third party plugins, like Omnisphere, can’t even operate any higher than 48000, so in that case it isn’t even an option to go any higher. 44100 is CD quality, so you’re more than fine using that. ![]() These two options also help the buffer by processing directly from the selected driver and giving a slight increase of latency to smooth out any additional pops and clicks.įurther down the Audio Options page, you’ll notice a section that says “CPU.” You might have noticed that I have “Mix in buffer Switch” and “Triple Buffer” selected. The two “Multithreaded” options allow your CPU to use multithreading, which is a common feature for modern CPU processors. I won’t get into detail about what it does exactly, but it helps with CPU efficiency. “Smart Disable” was a game changer when this was introduced in previous versions of FL Studio.
