#High CPU Usage

Hello, My Vtube Studio is using around 30% of my CPU which seems kinda high. I use Sprout 2 Capture and have disabled both Virtual Camera and NDI which hasn't helped I also have my tracking fps on the lowest settings along side with my physics on the lowest settings. I don't know if that is still normal CPU usage with those settings

Good afternoon
30% CPU usage sounds about what I would expect with your CPU (AMD Ryzen 5 3400G, 4 cores - 8 threads)

#

I'm comparing it to my CPU which has 12 cores - 24 Threads and VTube Studio still uses 6 to 10% of my CPU

Ok thank you

I run a single pc setup with a 1060 in it

#

Vtube studio doesnt use allot of gpu usage

#

The issue I had with a double pc setup is that with very demanding games gpu wise the webcam would freeze (not vtube studio). So there were 2 posibilities for me get an iphone to run the tracking on it or use my old pc as streaming pc/vtube studio pc. I went with the later one since I still had my old pc.

So it will all depend what games you play. For some games what you have is more than enough. For others slowly upgrading is a good idea if you can afford it

#

beacuse a lot of the games I play are CPU intensive and not GPU intensive

low mountain
#

If thats the kind of games you play, yes

#

But if those games run fine now, it might be an idea to buy a 2nd hand iphone (with the right tracking). It will take some load of your pc.

It's a complicated puzzel

#

When i was with one pc setup I had a i7 13700k and a rtx 3090 and it still froze in some games

the image I sent was using my iphone for tracking

#

Beside vtube studio being at 30% cpu. If you dont open your task manager do you have issues? It's better for your cpu to work than have a beast that stays at 5% 😋

#

With issues i mean your game or stream lagging

hidden cloak
#

and I can't go above 30fps on stream or else my stream will lag even worse

#

Also, like the few browser sources I have I have frame capped at 30 fps to try to help it a little

low mountain
#

Then you indeed might need to start to think about upgrading

#

You are using nvenc as your encoder in obs, right?

hidden cloak
#

yeah

#

I can send a screenshot of my preset

low mountain
#

Its alright, I believe you

#

Mmm upgrade time 😁

hidden cloak
#

Yep...

#

Like you can see in my settings I am streaming at 720p not cause my internet can't handle it, beacuse my pc is just weak

low mountain
#

One last thing. Did you checked in the obs logs if the frame drops are from too low cpu resources or from network instabilities?

hidden cloak
#

and they both go up at the exact same time to the same postion when I drop frames

low mountain
#

Mmm

#

Obs and vtube studio are run as administraror?

hidden cloak
#

VTube Studio no OBS yes

low mountain
#

You should. It allows to ask priority for resources

#

Still it might help a little but wont help your frame loss in obs

#

!administrator

hidden cloak
#

rip bot

low mountain
#

!admin

unborn shellBOT
low mountain
#

Hehe

hidden cloak
#

Ok I enabled Admin on vtube studio it kinda worked for lowering cpu a little

low mountain
#

I think we checked everything we could. If someone else has an idea I hope they give a reply too

gotta point something out

#

You might have overtuned nvenc

#

The difference between each preset is going to be about 10% on the actual GPU usage, but it wouldn't really be an issue for the 3050, only the 1060

#

If you are doing a 2-pc setup, how are you transferring data from one to the other?

#

At any rate

#

the iphone should be the better tracker, and using the webcam will peg one CPU core 100%

#

Can't be avoided

#

So if you have a quad core, 25% is just going to be OSF runnin

#

I've run VTS on a 2012 macmini for giggles before, and it works fine there. The problem will always be the nature of the device it's run on. The more you run on a single computer, the more potential pitfalls.

#

If the CPU usage is a large concern, upgrading the CPU and GPU , in that order

#

If you are doing just "just chatting" streams, then I'd not worry so much. It's usually the games that will make things fall over.

#

That's why people with weaker systems, who have a capture card, usually play console games

#

Hi, I mistook which side of the conversation I was reading, as I usually look at the log file for issues

#

okay, double-checking, The 1060 3GB is probably on the weaker end, but is fine to use NVEnc on at recommended settings (eg 6Mbit, 720p60/1080p30) That won't impact the CPU in OBS, but if you are re-scaling a layer, that imposes a CPU penalty. If you have your OBS setup with a 1080p canvas, then all the layers should be 1080p sized to avoid additional rescales. If you are streaming 720p, rescale it once on the canvas page

#

VTS will usually peg 1 CPU core when using webcam/mediapipe, and that is unavoidable

#

If you're using the iphone, then that should be a non-issue

#

On my PC (i7-11700k) VTS uses 7% which is equal to slightly more than one thread on the CPU. So if you have a quadcore, 25% would not be unusual, but that CPU has 8 threads, so I'd expect maybe it topping out at 14% at idle.

#

Hi, please turn "on" the logs in VTS, run the app again with the iphone tracking, and then send that log file. When logs aren't turned on it doesn't show the debugging information about frame rate

#

It's running at 120fps

#

do you have a 240hz monitor by chance?

#

Set it to 30fps, check the CPU, then set it to 60 and check again. It should be around 3-8% CPU, at most

Yep, then this was it
