Question / Help High CPU usage and stuttering

Hello guys.

I run with an FX-8350 Overclocked to 4.5Ghz(temps and such are fine) but I've noticed when playing BF3 that the cpu usage is up towards 70-85% while I'm on ~70-100FPS ingame. However, I've also noticed stuttering(lagspikes time to time) when playing BF3. It works just fine for any other game.

My speccs:
CPU: AMD FX 8350 @ 4.5GHz
GPU: GeForce GTX 650Ti BOOST 2048MB
Motherboard: Asus SABERTOOTH 990FX R2.0
Memory: Corsair 8GB CL8 1600Mhz VENGEANCE

Settings ingame + stream:
Resolution: 1920x1080(ingame) - 1280x720@60fps(stream)
Everything set to low in BF3
Quality Balance: 10
Bitrate/buffer: 3500(both)
Audio Encoding: AAC / 256bitrate
Server: London, UK(Secondary)
Preset: Veryfast


Would you consider this normal when playing a game like BF3?

Thanks

The Usage of the CPU seems to be okay and with your frames you shouldn't be experiencing any lag.

In Broadcast Settings, do you have Minimize Network Impact checked?

As for stuttering, when it wasn't my CPU maxing out and crapping on me, I found out that it was because of my Bitrate/Custom Buffer settings. I'd try turning on CBR and unchecking the Custom Buffer and see if that does any justice.

If anything, drop your Bitrate down to 2800 and leave your Custom Buffer where it is and see if that changes anything. I don't know much but from past experiences, whenever my Bitrate and Buffer were the same, I stuttered like CRAZY.

This is all just my opinion though, I'd wait for someone more experienced to Chime in, however if you have nothing to lose, give it a try. Your log looks fine to me.

(This is ingame lag/stutter right? Not ON the stream?)

Switching to CBR and disabling Custom Buffer Size... is a good a place to start as any. Given the fact the log seems to be fine. But yeah, give that a try and see if it improves.

If all else fails you could also just walk through my Troubleshooting and Startup Guide, following it step by step and see if that resolves something.

I do not have Minimize Network Impact checked, no. Should I check it? :p
I've checked the CBR + uncheck the custom buffer so I will try it out.

And yes, this is ingame stuttering and not on the stream.

With his hardware there really is no reason to disable Aero. The only circumstance when one might need to disable Aero is when Monitor Capturing and that is just a last resort method either way.

Okay, I've gamed for a little over an hour while having the stream on "preview" and I noticed a difference, but I can't say if it was big or if it was small...

This is when using "Use CBR" and the other settings you told me I should try.
But all I can say, it felt like it made a difference, but I'm not really sure since I had some lagspikes/stuttering in the end(due to more people joined) I get the suttering when dropping fps btw. I drop from XX to -10 of that number pretty much.

I was wondering though, with the CBR checked, doesn't that mean the quality will suffer?

CBR will drop the quality, a bit. But conversely, it will stabilize your stream and prevent any spikes from either causing you to drop frames or your viewers experiencing lag.

Anyhow, that latest log looks just fine. If you still notice some lag spikes, frame drop you could consider dropping the bitrate in steps of 50 Kbps until it's completely smooth.

livestreamed for 5h today and I still have SOME stuttering. Not as much as I had yesterday though. So it helped and the quality is just fine with the CBR activated.

So I thank you all for the help I've got.
Another question though: Do anyone of you know anything I can use that lower the musics volume while I talk, but makes it higher(to a surten level ofc) when I don't?

That's when someone else is talking.
Or rather, it reduces the sound completely when I'm in a call on skype etc.

If I didn't explain correctly, I'll try again:
I like to have a bit of higher volume when playing games, but the chances of the music over-voicing me when I'm talking to the stream is quite high, so when I'm talking I want it to reduce the volume of the music.

I did understand correctly and as far as I know that functionality of Windows actually works both ways; ie -- also when you are talking.
