It's been in Cubase since they implemented VST3 15 years ago...and it's STILL needed--the ability to disable the dynamic reallocation of CPU that's built into the VST3 (and AU) standards.
If you engage a VST3 plug in, it needs to burn, whether it has audio flowing or not. Otherwise...you get what I had recently upgrading to 7.2 from 4.3...it couldn't even play BACK my 4.3 sessions same machine/audio hardware without bumping the process buffer to like 2048. It normally sits at 512samples@96khz. The readout would go 73%....over....91%....85%...as it's playing--causing underruns the whole way. On 4.3 (and thus VST2) it could pur along at 95% without a single overrun. I mean that specific one (with referenced numbers) was more like 88%, but...you get the point.
It's a simple check box in the prefs (on the user end):
"VST3 plug ins suspend processing when audio isn't present"...I uncheck it.
You would think it makes for more headroom in the CPU, but 15 years later, it does NOT....
For the moment, I've tried to hide all my VST3 and only use VST2.
