I know there have been a 1000 of these threads but I really cannot figure out for the life of me why im getting these spikes.

My OBS Cpu usage normally floats around 15-18 which from what i've read is normal, but every few minutes it skyrockets to 25-40 and it kills my framerate. I've tried everything that I can think of and read online. Thanks in advance.

Try using the 64bit version of OBS for more encoding performance and lower it's priority so the game threads don't get stalled by OBS's threads.

Derkyy · Feb 22, 2014

I'm going to start using the 64 Bit OBS, but neither of these fixed my issue ;/

Lain · Feb 22, 2014

You're streaming at kind of a high resolution. Perhaps just try a tiny bit more downscale?

Derkyy · Feb 23, 2014

I attempted to downscale the resolution as well to multiple different resolutions nothing helpped.

Lain · Feb 23, 2014

Downscaling didn't help? Very strange, seeing as that's the most direct way to reduce CPU usage. Do you have a new log from that session?

21:05:33: successfully capturing d3d9 frames via GPUhttps://gist.github.com/f4fe8299a574629b22a5

There was some dropped frames and I know what the cause of that was and there also some changed settings (x264 cpu preset) I was merely trying to get different results... which I did. My OBS Cpu usage was around 5-8 constantly and when I'd get the fps drop it'd only shoot up to 11-15% CPU usage, but my CS:GO FPS would drop from 200 to 40 during said spikes.

I've seen some sort of CPU throttling happen with CS:GO specifically in some rare cases, though I have no idea what causes it when it does happen. I've seen a similar case at least once or twice before where CS:GO's FPS would just drop for no reason even when OBS wasn't even really encoding all that much. I would recommend trying more downscale again just as a test.

I'm not entirely sure what to suggest at this point because I'm just as baffled as you are. Maybe there's something else causing this? The only thing that OBS spends CPU cycles on is encoding, and OBS uses the most common h264 encoder known to man, so I really don't think it would be caused by that, though who knows for sure at this point.

Well first off I appericate you taking the time to try to figure this out. But CS:GO isn't the only thing thats giving me these CPU spikes tomorrow I should have access to another CPU and i'm going to swap it out and see if thats my issue mainly because I've seen other issues when it comes to streaming and the FX series AMD CPUs... So who knows. And as for trying more scaling i've gotten all the way down to 480 and it still gives me the same issues.

Derky try disabling core parking, it can help with stuttering and spiky CPU usage. It definitely helps with Bulldozer and newer AMD processors.

That aside I've had problem with .612b, try using .60b as well and see if that fixes things. I didn't look at CPU utilization, but I was getting hard locks.

Not sure which one worked but I tried both and its working FAMOUSLY! Thank you for your help and thank you Jim

**I tried on cs and it worked great along with Dota 2 but , I loaded up rust and I got the high CPU usage stutters again.
*** Played cs again few hours later... getting the same stutter.

tried messing with more settings to no avail

Though no related to OBS I do get spikes while playing BF4, it normally sits around 50% CPU usage and when I get FPS drops it goes up to around 60% so possibly i'm not getting enough power to my CPU?

Bensam123 · Feb 24, 2014

Could it be your CPU is throttling itself and the spikes are due to a reduction in CPU frequency? I'd keep something like CPUZ open on another screen so you can watch the frequency of your CPU while playing.

I stream 720p@30 with a 8350 and it sits around 16% CPU utilization. Sometimes a bit higher, sometimes lower...

Well after a lot of troubleshooting I figured it out ( kinda ) after monitoring my CPU status I was noticing my CPU would drop from 4.1ghz to 1.7ghz and my volt would drop to .9 volts almost as if the AMD Cool n quiet feature was on ( which it wasn't ) so I set my CPU to a static frequency and voila it is working like a charm, I appreciate everyone investing some time in helping me figure this issue out.

Bensam123 · Feb 28, 2014

Yup... something to consider is updating the bios. You may have a older motherboard which doesn't fully support a 8350 without a flash. Otherwise it could be temperature throttling.
