Hi
I’ve just been alerted that my CPU usage (50%) in the Audio Performance Monitor is down to the VSX plugin in the Control Room .
Has anyone else had this vast CPU usage with the VSX ? If so is there a work around ?
I’ve just tried a work round of putting the VSX plugin the master out. When I export ill get rid of the plugin as it’s for analysing only.
I have VSX as a Control Room insert (CB14 Pro / Win 11) and I have no issues with CPU overload or latency.
Does it take into account the soundcard or the way outputs are set ?
I’m a bit baffled. I use an SSL2 + II usb interface.
I don’t know of any settings that could change things.
Not sure how I can help - I use a Focusrite Scarlett 4i4 4th Gen.
This are how my connections look:
and my control room:
I’m running on 48k/128
Thanks for taking the time to do that. Mine is exactly the same. I had a presonus and then a Axe I/O. At the moment I have the SSL 2+ but, they’ve all been the same even with a different motherboard because I thought the pc was getting a bit old for Cubase 14 Pro.
What is your situation regarding GPU? Different cards seem to have odd effects on Cubase.
I have a Nvidia GeForce GTX 1050 Ti which is pretty basic spec compared to many cards, but the studio driver (not the GeForce Gaming pack) with this has made a huge difference to the performance of what was a new and expensive PC a couple of years ago.
It was a PC Specialist build, but the GPU they used was a real entry-level job, and it took me ages to work out what was causing the poor performance.
Not saying this is the issue in your case, but if you have suspicions about the PC performance, generally, a GPU upgrade can work wonders.
Who built that one, @manassas77 , and how long ago?
(I’m looking at buying a pre-built system, that’s why I’m asking. If you feel more comfortable replying by PM, that’d be cool also 
, thank you!).
It was January 2023 - and I asked for advice from the forum. This is the thread:
(Coincidentally, I must have noted the CPU hit from VSX !! Can’t remember saying that!)
PC Specialist did their job, but I did have numerous problems for a month or two after that, eventually finding that the memory was too fast for the SSD drive, and the already highlighted inadequate GPU, so it wasn’t all plain sailing.
I think when you are specifying the build on their website, there is little help or advice around, and even with the forum help I didn’t get the perfect machine straight away. Two years on, the PC has settled into a rock solid unit and Cubase 14 rarely falls over.
Short answer - yes, PCS worked, but not without issues.
@Thor.HOG you Mac guys never miss a chance to have a go at us second-class citizens with our PCs, huh?

I’ve got a Ryzen 7 set up with the graphics onboard the CPU chip. I’ve had trouble before with Nvidia drivers
Yep - It is a minefield for anyone wanting to spec a PC at the moment. I was lucky, AMD and Nvidia play nice with each other, but others haven’t had the same experiance with their setups.

Whats your buffer size? Does the situation improve if you set a higher buffer size?
The control room is always in the low latency path, not in ASIO guard with its extra buffer, so the CPU usage of anything goes directly into the realtime value of the performance meter.
My buffer is 64 so I get latency of 2 in and 2 out.
If i raise the buffer yes it does lower the Real Time and peak.
The thing is if i use the VSX in the master output of the mixer there’s no problem at all.
Yes, that is to be expected, if you have VSX on the master bus - and no track is record or monitor enabled - that goes through the extra buffers of ASIO guard, and thus no impact on the real time meter.
If you put any track into record enabled, this should change, as then the master bus also runs through the realtime path.
64 samples is really low - I would expect to have some issues at that rate.
All depends on the audio interface - my Focusrite 4i4 runs at 128 samples and has virtually zero latency when recording audio, but my older Yamaha sound card (and a Komplete Audio I had for a while) would struggle to keep up at 128.
At 128 The Real Time and peak are 20 and 25% and the latency is 4 in and 4 out.
I’ve loaded a project and the same happens with vsx in the control room but not in the master out fader,
I’ll just use vsx in the master output as I’ve found in the past you can waist a lot of time chasing things like this.
That should be fine - VSX software will automatically be bypassed when you export audio. Obviously this means you can only output to headphones, rather than to the mains.
