Hi!

I have a problem, ultimately when I record with OBS, I I have these peaks FPS (without loss of frames in OBS). Previously not happened to me, this is about 2 or 3 months going on.
This happens approximately every 1:50 minutes for 4~ seconds since start recording.
(When I record with Mirillis Action! this does not happen).

My PC
  • CPU: OctalCore AMD FX-8350, 4119 MHz (20.5 x 201)
  • GPU: AMD Radeon HD 7850
  • RAM: 8GB (Kingston HyperX KHX1600C9D3 x 2)
  • MB: Asus M5A78L-M LX Plus
  • PSU: Cooler Master Extreme 2 725W

log for this record
log of livestream (also happens)

EDIT

Change the thermal paste (Maybe get WATERCOOLING) - It's works (technology Cool'n'Quiet)
Reinstall Windows 7 - didn't work
Set x264 CPU Preset to ultrafast - didn't work (still happen every 2.5 or 3 minutes)
Set Process Priority Class to Idle or High - didn't work
Reduce Bitrate - didn't work



An apology for my bad English, I hope you can help me.

Greetings.

Re: Sometimes lag/fps spikes

I actually don't have a solid answer, in your logs OBS is reporting everything running fine on pretty much all fronts. Though I could present some theories. One theory, assassins creed 4 is a game I just recently beat, and it's pretty intensive on the system (graphics and CPU both). It could just be that assassins creed and OBS are fighting over system resources.

Thanks for the reply, it's very frustrating not knowing what is, this happens with all games (I think it's something about the motion) not only with Assassin's Creed BF.
Also happens with XSplit software.

Re: Sometimes lag/fps spikes

the gpu itself is not the real problem its just a weird thingy going on as soon as you try to stream noone could explain it noone will probably ever be able to something about the 78xx series doesnt work as intended ... but for pure gaming performance this card is the shit for its price

if you wonder how i fixed my problem ... i bought an gtx 770 :/ never had any fps problem since then.


you could try lowering your ingame settings or try using vsync

Re: Sometimes lag/fps spikes

Is there a reason you are using window capture opposed to game capture? You could also try enabling opencl in custom x264 options. Go to advanced and and enable the box for custom parameters for x264 and type "opencl=true" in the box. This actually increased the performance on my radeon 7850 when streaming, reducing load and spiking. Also disable CFR in advanced, there is really no use in having that enabled unless you are going to be editing your videos.

Also how many scenes/captures do you have set up?

Problem Found

The problem is the CPU temperature, I have monitored the CPU temperature when these FPS spikes happens. When the temperature reaches 74°C (I know this shucks) the system reduces the CPU Operating Frequency (this increases the percentage of use by OBS or XSplit) and causes FPS spikes.

The solution was to change the thermal paste, with plans to get WATERCOOLING.

Thank you very much everyone for your answers, I hope this helps future cases.

I love you guys, nice software.

weird .... 74°C is actually quite low for an amd under load with only the boxed cooler except if you changed the throttle temps

No alpinlol, the throttling of AMD FX cpu's start at 70*C and they do not use thermometers on their newer AMD chips so the temperature readout of like alpine/hwmonitor/sysmonitor will be a 7-10*C difference, basically 74*C would be roughly 80*C. Im not saying his temperature is wrong but there could be a difference. Also im pretty sure the new fx 8core series processors have a heat limit of 61*C and then they start throttling. 74C* on a fx 8350 is not a safe temperature. It also depends on your motherboard.
