Question / Help OBS cpu usage suddenly sky rockets

Hi

I recently started experiencing a major rise in my cpu usage whenever I begin my broadcast or even go to the preview mode. Without OBS running my games run as smooth as ever but while trying to stream I get a cpu usage of 90 to a 100% I've been using OBS with the same settings for close to a year now and this only seemed to start happening after the latest update. The same games I've streamed before without a problem in performance I cannot even run on medium or low graphics anymore. Suddenly everything I play on the PC is practically unstreamable. The games that I tried running during the time this has happend are H1Z1, Dying Light and Hatred for example.

The settings I'm running are pretty much the same that are described here, with a max bitrate of 2500kbs, 30fps and resolution downscaling to 720p. The other tips don't do anything for me -> https://obsproject.com/forum/thread...ing-too-long-to-encode-read-this-first.23334/

I also had one crash while this was happening. I think I was alt tabbing from a game to obs while it happened. The crash log is included.


Also the latest OBS logfile is here: https://gist.github.com/c5457e5470085605031a

Any idea what could be causing this? Thank you!

Enable aero, use game capture, remove the monitor capture completely, dont "Syncing audio to video time", and lower your webcam resolution to no more thant 720p. Lastly, I personally would put both your monitors on your dedicated GPU (the GTX 660), no reason to even use the onboard gpu.
 
Tried all of this. Very very minimal help. And as I stated, none of this was happening with any game until last time OBS got updated, even with the things you guys mentioned as they were. Anybody know if there was some kind of a major change with the latest version of the software or sth? Also wondering if this would be a non OBS related issue but I can't think of anything that I would've changed on my pc lately

Can you post a new logfile of you streaming or recording for at least 5 minutes?

There you go. The monitor capture you guys mentioned is in there, but I tried disabling it earlier and it didn't do the trick. And it's only in another scene outside the gamecapture one and has an area of 500 X sth pixels. Could it still potentially affect the performance even tho it's on a different scene (just a side question)

It wont affect as long as its not a global source. you still have yet to enable aero. that is a two step process. First make sure that disable aero in OBS is Unchecked then chose a windows aero theme. it doesn't have to be a super glassy theme. just a theme that will enable aero in windows as well. you'll see the difference once you switch. after you get it enabled, post another logfile with a similar 5 minute stream. Also, whats your CPU usage at while you stream?
