So I've started using OBS Studio, until I realized that when I stream to Twitch. My CPU goes from 15-20% (Without streaming.) And as soon as I start streaming. My CPU skyrockets to 95% - 100% and I can't stream. Now with OBS (Both OBS version are 64bit.) Regular OBS has my CPU around 30% - 50% usage.

Image is CPU usage without streaming. Again OBS (64bit)

The next 2 images will be OBS Studio during, and without streaming.

As you can see my CPU reached a level of 85% usage during the stream. Now it fluctuated from 45% - 85% when I took this screen shot. Now I'm not sure whats causing my CPU to reach such high levels.

And when I'm not streaming my levels have reached a high level of 40%

When I stream to Youtube, beam.pro. My CPU usually sits around 35% during a streaming session. Now I heard this would be caused from Twitch sadly still using Flash player instead of using HTML5. Can someone help me out.

If I've missed something in the threads, please point me in the right direction. Or any article related to the same problem.

OBS MP doesn't encode while no outputs are active, so if you get such high CPU without streaming then you have a really CPU intensive source (probably a webcam running at 1080p or something).

iGame360 I get the same problem man. I'm running Mac. Multiplatform ran so smoothly only using about 5% max CPU during recording or streaming. Now it uses around 30%. I just tried to stream (Minecraft) and I was getting block lag like I was on a really crappy server (was just doing single player). I wish they'd give us the option to roll back to the Multiplatform. If not I'm going to have to find another program. Sad because I really liked OBS and was excited when I read the change log for the Studio update. I even tried changing a few settings to use less CPU and it's done nothing. :(

I have this issue with some device drivers; one of my cap cards, when active by any program, locks in 100% CPU load. Doesn't affect anything else on the machine, encoding works fine, nothing bogs down at all (so I'm guessing it's low-priority/nice'd), but CPU temps spike just like it was running Prime95. Switch it off, and everything goes back to normal.

Could be the same thing with your webcam somehow. Try removing the cam, or check CPU load with another program that uses the cam, like Skype or something? See if it does the same?

There's also only one logfile there, we need it from both to compare and evaluate. :)

The most likely cause is that you're using different settings between the two versions, whether you've realized it or not.
