Question / Help High CPU usage (i7-4770k)

WolfsGoRawr · Feb 16, 2014

Hey guys,

I was streaming some Titanfall and when I got my transcoding options on twitch I fired up the bitrate from 1800 to 3k.
And I started to notice FPS drops and such due to my CPU hitting near 100% usage on cores. (I don't use any OC or anything)

I've got a fibre optics connection that is stable and tested and is not the cause if the problem (100/100)

CPU - i7 4770k
GPU: GTX 780
Ram: 16gb corsair vengeance
PSU Seasonic-x 750w
Mobo: Asus maximus vi hero

OS: Win 7
OBS: 64 bit

I've had the same isse a while back with TF2.

When I stream on 1800 bitrate my CPU is using roughly 60 to 70% of my CPU.

I can't figure out why as I use the following settings in my OBS.

- CBR &CBR Padding.
- Bitrate 1800 to 3k+ which is when trouble starts.
- AAC, 128bitrate, 48khz stero

- Resolution Downscale to 720p on Bilinear (fastest)
- FPS 45 (makes it look a lil smoother without pushing the 60 fps load
- Aero disabled

- Multithread optimzations enabled
- Scene buffering 700
- x264 cpu present: Faster (I don't even dare to touch medium)
- Encoding profile main
- Keyframe interval 1 second.
- CFR enabled

Anyone have a idea?
- I do use all the latest drivers on all my hardware, and run the latest bios as well.
- I do NOT experience overheating on any part in my PC and they are not being throttled due to that.

Have you tried putting the x264 CPU preset to the next setting up? I think it is very fast.

WolfsGoRawr · Feb 16, 2014

ofcourse this is taking the load off the CPU.
But other people running with the i7 4770k are getting lower loads on 60 fps and the medium preset.

It seems a lot of people with the latest build of OBS have CPU spike issues.

Update:
I tried using a custom resolution of 720p
Switched the keyint to 2
And went to a lower resolution webcam.

Still on faster and fast presets and playing a game like titanfall I wreck up 90%+ loads and on moments FPS drops on 45 fps as other people are playing triple aaa titles on 60 fps on medium with no issues on the same processor.

It seems a lot of people have CPU spikes these days. Something with the latest build with OBS?

Obvious one, enable Aero. It speeds up window capture significantly.

We'd also need to see a log (minimum 5 minutes) where the whole thing is at 3000kbps; changing it mid-stream is possible, but makes it a lot harder to troubleshoot. I'd also say that Titanfall could definitely be a source of an issue; as it is beta, it may be misbehaving a bit now and then.

I'd also advise monitoring your Process list on task manager, as well as your CPU stepping rate and temperature. If it steps down for some reason, that could explain the maxed out utilization.

Confirmed, I'm entirely able to run TF2 at 1080 with a 720@60 downscale at 3000kbps on a first-gen Core i7 920. Including on the latest OBS. Seems like it's an issue with the system that needs to get run down.

WolfsGoRawr · Feb 17, 2014

I don't really use window capture anymore, it always gave me issues with Isaac so I kept it disabled. Ill enable it again.

my log is indeed changed several times mid stream.
Ill try to rock the 3k.

I can run 720@60 3k fine as long as I stay on very fast or something.
You would expect an i7 4770k to rock that near medium though.

So my system is fucking up. Wonder what part is dying now #Paranoid

I did monitore my Temp's for most of my stream after I started having some issues.
(which is when I fired up the bitrate.) And the temps are way below any kind of critial heat. They sit roughly around 60 to 70 degrees at max loads.

No clue how to check for "stepping" rate

WolfsGoRawr · Feb 17, 2014

As Ferretbomb suggested:

a longer stream with 3k+ bitrate!

I still have highloads like this, getting in the 70% and sometimes 80%
My CPU is suppose to rock medium just fine!

Another caster told me to use my integrated graphics to make quicksync an option so I can stream with the medium preset and very low cpu usage. Should have the same~ish quality then compared to what I generate now.

Also I've been told I experience minimal screen tearing every now and then on my cast.

I have a 4770k and it can do 720p on Medium... if its doing NOTHING else! You're playing a game, a game in beta, a game that uses CPU itself and is probably pooly optimized. You can't do them both at the same time!

Second, turn Constant Frame Rate back on! Turning it off just disguises problems and makes Twitch and any video editors mad.

Third, a little trick you might be able to use: on the Advanced page, add "threads=9" to the command line for x264. By default x264 opens 12 threads, which in my testing is too many on a 4 core + hyperthreading like your 4770k.

A lot of people that use the i7 4770k rock decent bitrates on triple aaa titles on medium and 60 fps with no problem on their end. Hence I'm worried.

I prefer CFR on as well, I just tried to see if that was a possible cause for my high CPU (It was not)

I don't know about the custom encoder settings to just randomly try it. can any respected source confirm?
- and ofcourse people from OBS, check my latest log if you can find anything that could explain all the things!

Er... your first log file showed a number of window captures being used throughout the testing. Likewise with the most recent log, shows a window capture in use. Though Aero on now, so that's an improvement.

Also, QSV is something you'd have to play with and test. Hardware encoding is going to decrease quality (noticeably). QSV is more of a crutch to allow underpowered systems to both stream and play at the same time, sacrificing a bit on how the stream looks to offload CPU usage. Some people just throw it on and don't give a crap, then others parrot the advice without knowing any of the down sides, doing any testing, etc. You'll get poor image fidelity with QSV as compared to standard CPU-based encoding. Had someone else complaining yesterday that his stream looked like shit... and he was using NVENC because someone told him to do it, and he couldn't understand why he was getting pixellation and artifacts all over the place, running at 3500kbps. Then proceeded to argue that it couldn't possibly be the NVENC, because XYZ told him so.

I can stream BF4 all ultra at 720p30 using the medium preset and "threads=9" on my 4.2Ghz 4770k.

I use window capture for my Twitch (pop out) chat, I don't use it for games or anything else.

Aye, I always thought QSV was only used for 2 pc's but somebody said it really helped him out in a setup of 1 pc but with GPU + intrgrated graphics. I'm not eager to go down that road as I should be fine with my processor right?

And I don't understand the costum encoder setting "threads=9" either. What is the actual effect, do I lose quality etc etc. Because if it is a known bug in the current encoder, why would OBS not say anything about it in their program itself when they Detect a quad core CPU? nor can I find a OBS post on it.

Videophile · Feb 18, 2014

The "threads=X" option limits how many threads OBS(X264) can use. By default, X264 will use 1.5x the cores you have, so 12. However, your computer only has 8 real cores, so opening more threads is not necessarily better. Limiting the thread count can help with performance, and actually increase performance sometimes.

Boildown · Feb 18, 2014

More specifically, the CPU only has 4 real cores, doubled to 8 with hyperthreading. But those 8 cores aren't as good as 8 actual non-hyperthreaded cores, but x264 doesn't make the distinction. And when you multiply it out by 1.5, its just too many threads and actually slows things down somewhat.

Interesting note: I run two instances of OBS at once, and when I do that I get my best performance by keeping both OBS instances at 12 threads. Which I would think means there's 24 threads at work. Which doesn't make any sense whatsoever why that would be better. Yet the evidence is conclusive, I get better performance with two OBS instances open when I don't limit the threads on either one. Maybe x264 somehow detects both instances of OBS and only opens 12 threads for the both of them, I dunno. I've experimented with 13 and more threads each and performance went down again.

So the thing to learn here is that theory be damned, experiment and use what actually works best, try to understand and write a new theory later. For many of us setting threads=9 (or threads=10) works (for one OBS instance in my case), but if you find otherwise, do otherwise.

WolfsGoRawr · Feb 18, 2014

Ill try the "threads=9" in my obs for todays cast.

I only have to put in: threads=9

Yes, correct.

WolfsGoRawr · Feb 18, 2014

I think I saw a small drop in load, but Still going all the way up to 70 to 80 frequently.

alpinlol · Feb 18, 2014

either titanfall is really a bitch and uses a shitton of cpu or theres something wrong since even my old sandy i7 2700k @4,5ghz can stream 720p60 on fast in most games ... and faster with bf4

Question / Help High CPU usage (i7-4770k)
