Hello i just recently built my computer yesturday installed windows and i wanted to use OBS to stream
But here was the problem i tried running it 1280x720 60fps and it was eating my CPU alive it was taking up 50 to 60 cpu
PC Specs:
AMD athlon x4 750k 3.4 overclocked at 3.9
EVGA Geforce GTX 660 2GB Superclocked
4GB Ram
Power Supply 500 Watts Bronze (Plus 80)

Can anyone help me i am new to OBS and i wanna use it instead of xsplit

Encoding is a very CPU intensive task, it's going to take up a lot of your CPU. Especially an old quad core like yours. I'm actually surprised you were only seeing 60% usage or so.

Well, are you noticing any actual performance problems? Your CPU being heavily used is completely ok.

Ok, that's what I thought. Don't use Monitor Capture on Windows 7.

The best way to stream LoL is to set up 2 scenes. In the first scene, have a Window Capture of the game lobby, and in the second scene, have a Game Capture of the actual game itself. Then use the Simple Scene Switcher to automatically swap between them: https://obsproject.com/forum/viewtopic.php?f=11&t=1785

You are also dropping a TON of frames, try another Twitch server or something.

CPU being high likely won't change, but again, only 60% is not bad. Hell, even 100% is fine if everything is still performing ok. Your problem was using Monitor Capture with Aero enabled on Windows 7 which is a horrible method of capturing and was ruining your game performance.
