A sampling frequency of 44.1 kHz or 48 kHz is fine for all purposes because you can run multiple instances of 3rd party
VST plug-ins with relative ease i.e., depending on how fast your computer is and which VST instruments or plug-ins effects you are using—don't forget oversampling too, whether you have it enabled on some plug-ins or not.
However, if you have enough processing power, run all FL Studio's projects at a 96 kHz sampling rate—your plug-ins will thank you for blessing them abundantly. On the other hand, 192,000 samples per second will make many VST plug-ins transform into little
demonic goblins in pretty much all DAWs.
Thus, 192 kHz sampling frequency it's a non-starter unless you are making one of those chopped-and-screwed records, then you don't have an option but to use high sampling rates otherwise you end up with garbage when you slow down stuff as much as other sound designers do as well.
